Pattern 3: MenuTroubleshooting Build ErrorsCopy pageAsk AI about this pageLast updated November 25, 2025You can troubleshoot build errors that occur during the Build step of your deployment to Vercel. This guide will help you understand how to investigate build failures and long build times. Troubleshooting views You can use the following views on your dashboard to troubleshoot a build: Build logs - the console output when your deployment is building which can be found under the Deployment Status section of the Project's Deployment page. Resources tab - the functions, middleware, and assets from your deployment's build. Source tab - the output of the build after the deployment is successful. This can also be accessed by appending to the Deployment URL You can navigate to these views from the Deployment page by clicking on the Source tab, the Resources tab or the Build Logs accordion as shown below. Troubleshoot Build failures If your build fails, Vercel will report the error message on the Deployments page so that you can investigate and fix the underlying issue. In the following we show you how to look up the error message of your failed build. Investigating Build logs Build logs provide you with an insight into what happened during the build of a deployment and can be accessed by: From your Vercel dashboard, select the project and then the Deployments tab Select the deployment. When there are build issues you will notice an error status next to deployment name Error status on the Deployments tab. On the errored deployment's page, you will see a summary of the error in the preview section. In the Deployment Details section, expand the Building accordion to expand the logs. There are situations where build logs are not available, in this scenario the error will be presented in the UI instead. Scroll down in the build logs until you find a red section where the keyword "Error" is mentioned. It can be mentioned once or multiple times. In many cases, the last mention is not indicative like in the example below where it says . If you look a few lines above, you will see an additional error which in this case indicates where the problem is with a link for more details. Sometimes, an error may not be mentioned in the lines above but the output will often help you identify where the problem is. Error in the logs of the Building accordion. It is recommended to build your project on your local machine first (the build command varies per project) before deploying on Vercel. This will catch issues specific to your code or to your project's dependencies. In the example above, when the command (that runs ) is run in the local console for a Next.js project, the error happens after building locally. Error in local console. Build Logs not available Builds can fail without providing any build logs when Vercel detects a missing precondition that prevents a build from starting. For example: An invalid configuration was committed When using Ignored Build Steps Commits were made from a contributor that is not a team member In this case, you cannot access the Building accordion described above, and instead, Vercel will present an overlay that contains the error message. Build logs not available for a deployment. Cancelled Builds due to limits Sometimes, your Deployment Build can hit platform limits so that the build will be cancelled and throw a corresponding error that will be shown in the Build logs. Review the limits below in case you run into them. Build container resources Every Build is provided with the following resources: HobbyProEnterpriseMemory8192 MB8192 MBCustomDisk space23 GB23 GBCustomCPUs24Custom For Hobby customers, these limits are fixed. Pro and Enterprise customers can purchase Enhanced or Turbo build machines with extra CPUs, larger memory, and storage. Exceeding the memory or disk space allocations limits cancels the build and triggers a system report in your Build logs, identifying memory and disk space issues. By default, the system generates this report only when it detects a problem. To receive a report for every deployment, set as an environment variable. This report helps you detect hidden Out of Memory (OOM) events, and provides insights into disk usage by breaking down the sizes of your source code, , and output, and flagging files over 100 MB. The input size in the report corresponds to the size of your checked-out repository or files uploaded by CLI. The size represents the total size of all folders on disk. ResourceAllocationDescriptionMemory8192 MBFixed memory allocation. Builds exceeding this limit will be cancelledCPUs4Number of CPUs allocated for build processingDisk Space23 GBFixed disk space allocation. Builds exceeding this limit will be cancelledSystem ReportConditionalGenerated in Build logs when memory or disk space limits are reached. Available by defaultForced ReportingOptionalSet as an environment variable to enable reporting for all builds Review the below steps to help navigate this situation: Review what package the error is related to and explore the package's documentation to see if the memory allocation can be customized with an install or Build command If no package is specified, look into reducing the amount of JavaScript that your Project might be using or find a more efficient JavaScript bundler Review what you are importing in your code such as third-party services, icons and media files Build duration The total build duration is shown on the Vercel Dashboard and includes all three steps: building, checking, and assigning domains. Each step also shows the individual duration. A Build can last for a maximum of 45 minutes. If the build exceeds this time, the deployment will be canceled and the error will be shown on the Deployment's Build logs. If you run into this limit, review this guide that explains how to reduce the Build time with a Next.js Project. Caching The maximum size of the Build's cache is 1 GB. It is retained for one month and it applies at the level of each Build cache key. It is not possible to manually configure which files are cached at this time. Other Build errors You may come across the following Build-specific errors when deploying your Project. The link for each error provides possible causes of the error that can help you troubleshoot. Missing Build script Recursive invocation of commands Pnpm engine unsupported A 'module not found' error is a syntax error that will appear at build time. This error appears when the static import statement cannot find the file at the declared path. For more information, see How do I resolve a 'module not found' error? Troubleshoot Build time Understanding Build cache The first Build in a Project will take longer as the Build cache is initially empty. Subsequent builds that have the same Build cache key will take less time because elements from your build, such as framework files and node modules, will be reused from the available cache. The next sections will describe the factors that affect the Build cache to help you decrease the Build time What is cached Vercel caches files based on the Framework Preset selected in your Project settings. The following files are cached in addition to : FrameworkCache PatternNext.js.next/cache/**Nuxt.nuxt/**Gatsby.js{.cache,public}/**Eleventy.cache/**Jekyll{vendor/bin,vendor/cache,vendor/bundle}/Middleman{vendor/bin,vendor/cache,vendor/bundle}/ Note that the framework detection is dependent on the preset selection made in the Build settings. You should make sure that the correct framework is set for your project for optimum build caching. Caching process At the beginning of each build, the previous Build's cache is restored prior to the Install Command or Build command executing. Each deployment is associated with a unique Build cache key that is derived from the combination of the following data: Personal Account or Team Project Framework Preset Root Directory Node.js Version Package Manager Git branch Let's say that under your account , you have a project that is connected to your Git repository on the branch for the production environment. When you make a commit to the branch for the first time, you trigger a build that creates a production deployment with a new unique cache key. For any new commits to the branch of , the existing Build cache is used as long as is under . If you create a new Git branch in and make a commit to it, there is no cache for that specific branch. In this case, the last production Deployment cache is used to create a preview deployment and a new branch cache is created for subsequent commits to the new branch. If you use Vercel functions to process HTTP requests in your project, each Vercel Function is built separately in the Build step and has its own cache, based on the Runtime used. Therefore, the number and size of Vercel functions will affect your Build time. For Next.js projects, Vercel functions are bundled to optimize Build resources as described here. At the end of each Build step, successful builds will update the cache and failed builds will not modify the existing cache. Excluding development dependencies Since development dependencies (for example, packages such as or ) are not needed in production, you may want to prevent them from being installed when deploying to Vercel to reduce the Build time. To skip development dependencies, customize the Install Command to be or . Managing Build cache Sometimes, you may not want to use the Build cache for a specific deployment. You can invalidate or delete the existing Build cache in the following ways: Use the Redeploy button for the specific deployment in the Project's Deployments page. In the popup window that follows, leave the checkbox Use existing Build Cache unchecked. See Redeploying a project for more information. Use with Vercel CLI to build and deploy the project without the Build cache Use an Environment Variable with a value of on your project to skip the Build cache Use an Environment Variable with a value of on your project to skip Turborepo Remote Cache Use the optional query parameter with a value of when creating a new deployment with the Vercel API to skip the Build cache When redeploying without the existing Build Cache, the Remote Cache from Turborepo and Nx are automatically excluded.Was this helpful? supported.Send

Pattern 4: MenuFramework environment variablesCopy pageAsk AI about this pageLast updated July 18, 2025Frameworks typically use a prefix in order to expose environment variables to the browser. The following prefixed environment variables will be available during the build step, based on the project's selected framework preset. Using prefixed framework environment variables locally Many frontend frameworks require prefixes on environment variable names to make them available to the client, such as for Next.js or for SvelteKit. Vercel adds these prefixes automatically for your production and preview deployments, but not for your local development environment. Framework environment variables are not prefixed when pulled into your local development environment with . For example, will not be prefixed to .
