Problems building for iOS (Missing corresponding projectid)

Hi

I am a high school student and I have just build a 2D game that I would like to publish to the iOS AppStore.
I don’t have a Mac.
I have developed the game on a windows PC and have now built it for iOS and uploaded the resulting directory to GitHub and linked it to CloudBuild.
I have setup the certificates, provisions and uploaded them to CloudBuild.

When the game is built it fails with the following message:

1: Signing credentials: Tutorial Builds (iPhone Distribution: Mischa abc-lastname (xyz-teamid))
2: ! build of ‘ios_tutorial2’ failed. build target ‘ios_tutorial2’ missing corresponding projectid in build config.
3: Finished: FAILURE

Can anyone help me and point out my mistake?

Thanks a lot

Mischa
