Build Fails Due to JavaScript Heap Out of Memory and Missing deploy-manifest.json in Amplify Deployment

[husamMousa]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/browser

SDK Version

^8.26.0

Framework Version

Reproduction Example/SDK Setup

export default defineNuxtConfig({
  modules: ['@sentry/nuxt/module'],
  ssr: false,
  sourcemap: {client: 'hidden'}
  sentry: {
     sourceMapsUploadOptions: {
        authToken: "my-auth-token",
        org: "my-org",
        project: "my-project-name",
      }
  }
})

Steps to Reproduce

• Push a commit that includes source map support using @sentry/nuxt on a branch connected to AWS Amplify.
• Let Amplify auto-trigger its build pipeline.
• The frontend build phase starts (e.g. pnpm build).
• During nuxt build, the memory usage spikes and the process fails with a fatal JavaScript heap out of memory error.
• Even though the build log shows "Build completed successfully", the deployment fails due to a missing deploy-manifest.json.

Expected Result

• Nuxt build should complete without exceeding memory limits.
• Source maps should be uploaded successfully.
• deploy-manifest.json should be created in the expected output directory.
• The deployment should succeed.

Actual Result

• Nuxt build fails with:
  FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

• Followed by:
  CustomerError: Failed to find the deploy-manifest.json file in the build output.

• This only happens when sourcemaps.enable = true in the Sentry module config.

Hi @husamMousa, thanks for writing in and sorry to see you experiencing issues during builds.

Could you try to disable source maps in your nuxt config: sourcemap: false and see if you're still running out of memory?

I'm not familiar with AWS amplify, is there an option to increase the available memory?

[husamMousa]

Hi @andreiborza, thank you for your reply.

I previously tried setting sourcemap to false. The build succeeded, but the sourcemap wasn't generated.

I also increased the memory size, but the problem persists.

This is possibly related to #13836 🤔
Can you tell us what the memory is that is configured? And how large are your largest build output files?
