Pages build fails without a logo.png in the repo

Builds failed on my project until I have added a logo.png to the project repo. Logo was optional before and should remain option.

Before:

https://git.drupalcode.org/project/easy_encryption/-/jobs/8477315

$ (ls -l . && ls -l docs/*) | grep logo # collapsed multi-line command
Cleaning up project directory and file based variables

ERROR: Job failed: command terminated with exit code 1
