Hello,

Today, while trying to deploy my Laravel PHP app on Google Cloud Build using App Engine Flex, I faced some errors:

This is the app.yaml file:

```

runtime: php

env: flex

max_num_instances: 1

resources:

cpu: 1

memory_gb: 0.5

disk_size_gb: 10

env_variables:

Hello,

I ran your app.yaml file but I was unable to reproduce your issue. I was, however, able to deploy Laravel in App Engine Flex with PHP following this guide [1].

Please try following these steps.

Kind regards,

Angel

Hello Angel,

I was able to find the source of the issue. I had a section inside the app,yaml as follows:

env_variables:

This was interpreted as null. Hence, the issues above!

However, now the cloud build is okay, but I get 500 Server Error. I don't even get any logs to know what is going on!

This is the URL [1].

Regards

Hello,

I tried the URL and I didn't find any errors, I get 200 response and get to the login page succesfully. Do you still have any errors?

Regards

Daniel

It's working now! However, I filed a bug here: https://github.com/GoogleCloudPlatform/php-docker/issues/534

Thanks
