Issue git deployment error: The task "ext-git-task\deployment" has failed.

Server operating system version

AlmaLinux 8.7

Plesk version and microupdate number

18.0.56 #2

I am using the Plesk-Git integration, which always works just fine.
However, since yesterday I am getting the following error when pulling during the "Deploying files" phase:

The task "ext-git-task\deployment" has failed.

What could cause this problem? Is there a logfile I can check to get some more details?

Thanks!
