Very non discript error: [INFO] Action failed with "Error: Not Found"

[Liquidmasl]

Just trying to setup this action and i encounter

  [INFO] Action failed with "Error: Not Found"

Sadly i have no idea what is not found, which makes it a bit hard to debug, die gist? the file?
or is it on githubs side and it cant find the action (that would be out of your scope of course)

If this is part of your action, a more descript error would be awesome!
