Wordpress on App Engine - ERROR: (gcloud.app.deploy) Error Response: [13] An internal error occurred during deployment.

[Michael Fawcett]

Following the steps to install Wordpress on App Engine Flexible environment, however, I'm running into an issue when deploying. It works fine in the local environment.

Seem to have searched everywhere but just can't seem to find a solution. Any help greatly appreciated.

This issue had previously been reported in Public issue Tracker. You could star the case to receive any updates on the fix. It seems that this issue is a result of Icon files. So, as a workaround I recommend that you delete these files.

I should note that the Public Issue Tracker is for reporting Google Cloud-end issues and feature requests.
