Step #6: > [email protected] stage-server /workspace
Step #6: > node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng run sf-mini:server:stage
Step #6:

How to access the logs above.

Also here is the build yaml:

steps:
- name: 'gcr.io/cloud-builders/docker'
  args: [ 'build', '-t' , 'gcr.io/$PROJECT_ID/firebase' , './dockerfiles/firebase']
- name: 'gcr.io/$PROJECT_ID/firebase'
  args: [ 'use', '$_PROJECT_NAME','--token', '${_FIREBASE_TOKEN}']
- name: 'node:12.3'
  entrypoint: npm
  args: ['install']
- name: 'node:12.3'
  entrypoint: npm
  args: ['install','--prefix','functions']
- name: 'node:12.3'
  entrypoint: npm
  args: ['link']
- name: 'node:12.3'
  entrypoint: npm
  args: ['run-script','stage-browser']
- name: 'node:12.3'
  entrypoint: npm
  args: ['run-script','--debug','build-server'] <== this one which cause problem
- name: 'node:12.3'
  entrypoint: npm
  dir:  'functions'
  args: ['run-script','copyAndRename']
- name: 'gcr.io/$PROJECT_ID/firebase'
  args: [ 'deploy','--debug', '--token', '${_FIREBASE_TOKEN}']
timeout: 2000s

build command from package.json

    "build-server": "node --max_old_space_size=16384 ./node_modules/@angular/cli/bin/ng run sf-mini:server:production",
    "stage-browser": "node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng build --prod --configuration=stage --aot --vendor-chunk --common-chunk --delete-output-path",

Answer 1

It could be a memory problem. There are several GitHub [1] [2] issues that that has error code 137 and they're able to fix the problem by increasing their RAM.

EDIT: As mentioned in the comment, you won't be able to access /builder logs because a separate VM runs the build steps.

However, this may help you understand what's causing the problem. The valid maximum memory value in Firebase Functions is 2GB but you are increasing your memory to 16GB (build) and 8GB (stage) using --max_old_space_size. This could help explain why you're getting that out of memory code.
