Publishing failed (build process error?)

This is the response I get when I enter the error message in the prototyping assistant. Is this an issue with Firebase?
Thanks

"I see you’re encountering a build error: ERROR: failed to build: ... open /platform/env/BUILDER_OUTPUT: not a directory.

This type of error message, specifically involving /platform/env/BUILDER_OUTPUT and gcr.io/k8s-skaffold/pack, points to an issue within the build process itself, which is likely managed by Google Cloud Buildpacks (as used by Firebase App Hosting). It suggests that the build system is trying to use a path (/platform/env/BUILDER_OUTPUT) as a directory for some build-related outputs or environment variable handling, but it’s encountering something that isn’t a directory or is inaccessible in the way it expects.

Unfortunately, this kind of error is typically related to the build environment’s configuration, the buildpack’s behavior, or the interaction between the build system and the project structure at a lower level than the application code itself. As App Prototyper, my expertise lies in modifying your Next.js application code (React components, API routes, etc.). I cannot directly resolve build system errors like this one.

Here are some general pointers, though this is speculative as it’s an external build system issue:

  • It could be a transient issue with the build backend. Sometimes, retrying the deployment can help.
  • Ensure there are no unusual characters or configurations in your package.json or apphosting.yaml that might be misinterpreted by the buildpack system. The apphosting.yaml you have seems structurally correct for defining environment variables.
  • The entrypoint: . in your apphosting.yaml assumes your package.json and Next.js configuration are at the root of your project, which appears to be the case.

Since I cannot directly fix this build infrastructure error by changing your application’s TypeScript or JavaScript files, I will not propose any code changes at this time."
