Cloud Build for Google App Engine - Flexible is failing with a generic 'exit status 1' - debug output shows issue in python files

[Claudio Vallesi]

I'm testing how to build a pipeline on GCP and after successfully deploying an Angular 6 application I wanted to add a websocket (socket.io) backend that will serve real time updates.

First of all the error itself, which is results of this command:

gcloud builds submit --verbosity=debug --config stage.cloudbuild.yaml .

[...]

Step #1: ERROR: (gcloud.app.deploy) INTERNAL: Internal error encountered.
Finished Step #1
ERROR
ERROR: build step 1 "gcr.io/cloud-builders/gcloud" failed: exit status 1

[ ... NPM saying it's not its fault yada yada ... ]

My local environment is:

• Node: 10.9.0
• NPM: 6.2.0
• OS: Windows 10

Seems like something is wrong in some python script in my local machine but honestly I don't know how I should fix this. Any help is appreciated.

The following is the app.yaml file (specifically stage.app.yaml):

service: mercury

runtime: nodejs
env: flex

instance_class: B1
manual_scaling:
  instances: 1

env_variables:
  MERCURY_PORT: 5001
  MERCURY_SECRET: [REDACTED]

network:
  session_affinity: true

The cloudbuild.yaml (specifically stage.cloudbuild.yaml):

steps:

- name: 'gcr.io/cloud-builders/npm'
  args: [ 'install' ]

- name: 'gcr.io/cloud-builders/gcloud'
  args: [ 'app', 'deploy', 'stage.app.yaml', '-v=stage' ]

And finally, this is the package.json:

{

  "name": "mercury",
  "version": "1.0.0",
  "description": "socket.io event manager",
  "main": "index.js",
  "scripts": {
    "start": "node index.js",
    "deploy-stage": "gcloud builds submit --config stage.cloudbuild.yaml .",
    "deploy-prod": "gcloud builds submit --config prod.cloudbuild.yaml ."
  },
  "dependencies": {
    "async": "^2.4.0",
    "body-parser": "^1.17.1",
    "dotenv": "^4.0.0",
    "express": "^4.15.2",
    "express-validator": "^3.2.0",
    "http": "0.0.0",
    "jsonwebtoken": "^7.4.0",
    "moment": "^2.18.1",

  }
}

Hello,

I recommend posting this on Stackoverflow as it is better suited for development questions since the post will have more visibility. Groups is more geared towards high level discussions about Google Cloud products. But if you suspect the issue is on the Google side, feel free to open a new issue here [1] to potentially have the App Engine Team look into it.

Thanks,

Thanks for the suggestion but I did it already before posting here as well.

Posting here was a suggestion I received from the official Twitter account for GCP: https://twitter.com/GCPcloud/status/1140954434635272192

No one is answering to the stackoverflow question while at least someone replied here which is honestly quite disheartening about how much support is given over stackoverflow.
