Cloud build failed

I’m trying to use cloud build for the first time in order to build the project I’m working on to Android and I keep getting the following error:

As far as I know my Assets and ProjectSettings folder are in the root of the project so I leave the Project Subfolder empty, since I assume that being optional it defaults to the root of the project but I still get this error.
Is there any other configuration for the build target that I’m missing?

Looking at your build log, it doesn’t look like the ProjectSettings/ folder got checked in. I would double check that you committed those files.
