Mention any other details that might be useful.

It is just not pushing. On push, I receive the following error on the git terminal -

remote: Processed 13695 files...
remote: ................
remote: Processed 15289 files...
remote: ..........
remote: Error: ENOENT: no such file or directory, open '/home/site/repository/vendor/bin/phpcs'
remote: An error has occurred during web site deployment.
remote: Kudu Sync failed
remote:
remote: App container will begin restart within 10 seconds.
remote: Error - Changes committed to remote repository but deployment to website failed.

Any idea what is happening?

The push is successful but it's failing during the deployment step.

Can you see if /home/site/repository/vendor/bin/phpcs exists via Kudu Console?

[blueelvis]

Yes. It was existing via the Kudu Console and it was failing to delete as well. Had to rescale the app service plan to get the storage unlinked correctly. Even restarting the web app did not fix this issue... I have seen some weird permission denied errors as well while trying to delete a file even when the container web app is stopped.

I had met similar issue.
My situation is same error and the file is symbolic link to not existing file in azure.
I replaced to actual file and problem solved.

[blueelvis]

@nickwalkmsft - It seems the issue is occurring because KuduSync is not able to traverse symlinks properly. This issue becomes more prominent when there is an issue with the Azure Storage in the backend which makes the storage read only for some time and deployments start failing.

I have raised an issue for Kudusync over here as well - projectkudu/KuduSync#35
