google app engine deploy error from gitlab runner

[Bilal Akmal]

I'm facing this issue when I deploy a node app from gitlab runner. I've separate service account which has permissions to deploy and access storage as well, but after successful deployment without any errors it's giving "Not Found" error when I access the web.

But if I deploy the same app from local system it works.
Please let me know what kind of issue might be there.

Here's my app.yaml

runtime: nodejs10

# env: flex

env: standard

automatic_scaling:

  min_instances: 1

  max_instances: 2

service: partner

network:

  session_affinity: true

Hello Bilal, 

Local development environment is different from App Engine runtime after deployment, in particular here your local environment is able to run the binary: GitLab Runner is designed to run on the GNU/Linux, macOS, and Windows operating systems. Other operating systems will probably work as long as you can compile a Go binary on them. In other words, you local environment offers the advantage of running GitLab Runner, which explains why your deployment on the local server runs as expected. 

As an alternative to GitLab Runner, you may consider Cloud Source Repositories.
