Standard App Engine project wrongly deployed as flexible

Question

I have had a few python apps running on App Engine standard environment for a few years, the last successful deployment being April 7, 2017. Today when trying to deploy an update using this command:

    gcloud.cmd app deploy --project <redacted-project-id> -v 5 --promote --quiet

I'm receiving the following error:

    Updated property [core/project].
    Services to deploy:

    target service:  [default]
    target version:  [5]

I enabled billing for this project and it attempted to create a docker as if I wanted to use the flexible environment.

Why it was creating a PHP docker for a Python project is a mystery. Is this a bug or is it a misconfiguration on my end due to recent gcloud component updates?

Possible solution: This appears to be a bug caused by deploying with gcloud.cmd. I am able to deploy one app using appcfg.py like this:

    python.exe -u "C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\appcfg.py" --oauth2_credential_file=C:\Users\Brian\.appcfg_oauth2 --application=<redacted-project-id> --version=5 update appengine

It worked on one app, the other app is failing with a similar error as above, "Bad Request Unexpected HTTP status 400".

Answer 1

I discovered the solution, it was on my end. The above errors are caused because my deploy script was providing the wrong path to my codebase when calling gcloud app deploy. It was executing one directory above the codebase, which results in the above errors. Hope that helps someone else.
