Accessing GAE deployed Angular app

Question

I recently was successful in my attempts in deploying my angular app code using bitbucket pipeline to GAE flex environment. Though the push was successful when I tried to access it from GAE, it throws me a 404 error like this

Error: Not Found The requested URL / was not found on this server.

This is my app.yaml file

runtime: python27
api_version: 1
threadsafe: true



handlers:
# Routing for bundles to serve directly
- url: /((?:inline|main|polyfills|styles|vendor)\.[a-z0-9]+\.bundle\.js)
  secure: always
  redirect_http_response_code: 301
  static_files: dist/\1
  upload: dist/.*

  # Routing for a prod styles.bundle.css to serve directly
  - url: /(styles\.[a-z0-9]+\.bundle\.css)
    secure: always
    redirect_http_response_code: 301
    static_files: dist/\1
    upload: dist/.*

    # Routing for typedoc, assets and favicon.ico to serve directly
    - url: /((?:assets|docs)/.*|favicon\.ico)
     secure: always
     redirect_http_response_code: 301
     static_files: dist/\1
     upload: dist/.*


     # Any other requests are routed to index.html for angular to 
     handle so we don't need hash URLs
     - url: /.*
       secure: always
       redirect_http_response_code: 301
       static_files: dist/index.html
       upload: dist/index\.html

This is my bitbucket pipeline

 image: node:9.11.1
  pipelines:

  custom:

   default:

     - step:

       script: 

         -  npm install -g @angular/cli@latest

         - ng build --prod
         - cp app.yaml dist
         - ls dist
         - cd dist

         - curl -o /tmp/google-cloud-sdk.tar.gz https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-190.0.0-linux-x86_64.tar.gz

         - tar -xvf /tmp/google-cloud-sdk.tar.gz -C /tmp/

         - /tmp/google-cloud-sdk/install.sh -q

         - source /tmp/google-cloud-sdk/path.bash.inc
         - echo $GCLOUD_API_KEYFILE | base64 --decode --ignore-garbage > ./gcloud-api-key.json
         - gcloud config set project $GCLOUD_PROJECT

         - gcloud components install app-engine-java

         - gcloud auth activate-service-account --key-file gcloud-api-key.json

         - echo $GCLOUD_API_KEYFILE > /tmp/client-secret.json  

         - gcloud config set project $GCLOUD_PROJECT
         - gcloud app update --split-health-checks --project adtecy-ui 

         - gcloud app deploy app.yaml

This is what GAE logs show and I cannot find anything meaningful from it

Could you guys help me out?

Few things changed with the latest version of Angular CLI. If you are using CLI version > 6 use the following yaml, this yaml makes sure the handlers for js and css files are correct (removing the .bundle and adds runtime)

runtime: python27
api_version: 1
threadsafe: true

skip_files:
- ^(?!dist)  # Skip any files not in the dist folder

handlers:
# Routing for bundles to serve directly
- url: /((?:inline|main|polyfills|styles|runtime|vendor)\.[a-z0-9]+\.js)
  secure: always
  redirect_http_response_code: 301
  static_files: dist/\1
  upload: dist/.*

# Routing for a prod styles.bundle.css to serve directly
- url: /(styles\.[a-z0-9]+\.css)
  secure: always
  redirect_http_response_code: 301
  static_files: dist/\1
  upload: dist/.*

# Routing for typedoc, assets and favicon.ico to serve directly
- url: /((?:assets|docs)/.*|favicon\.ico)
  secure: always
  redirect_http_response_code: 301
  static_files: dist/\1
  upload: dist/.*

# Any other requests are routed to index.html for angular to handle so we don't need hash URLs
- url: /.*
  secure: always
  redirect_http_response_code: 301
  static_files: dist/index.html
  upload: dist/index\.html
  http_headers:
    Strict-Transport-Security: max-age=31536000; includeSubDomains
    X-Frame-Options: DENY

On top this, you should also edit your angular.json (which used to be angular-cli.json) and set "outputpath" to just "dist" rather than "dist/your-app-name" for gcloud app deploy to pick things up correctly.
