In my plugin configuration I set
windows:
assets_dir: "${PWD}/assets"
Then I get:
AssertionError: Expecting only one image in /home/srak/project/win11/build/assets/windows
but also
ls: cannot access '/home/srak/project/win11/build/assets/windows': No such file or directory
This seems unintuitive, perhaps assets_dir should be the full path to assets?
