Hi @barthur1234,
Did you try to run this on your own development Linux box, using our CLI? How to experiment with Bitrise configs locally, on your Mac/Linux
Or maybe even in the bitrise docker environment ( https://devcenter.bitrise.io/docker/run-your-build-locally-in-docker/ ), which is the exact same environment your build is running in.
Running these locally can definitely help a lot with debugging issues quickly! 
Please let us know how it goes or if youâd have any questions!
