ambiguous argument 'origin/master' GitHub and TeamCity

Hello,

we use Github with our TeamCity and we are getting an error message we cannot get rid of:

+ build/deploy.sh
[08:59:41]
[Step 2/2] fatal: ambiguous argument 'origin/master': unknown revision or path not in the working tree.
[08:59:41]
[Step 2/2] Use '--' to separate paths from revisions, like this:
[08:59:41]
[Step 2/2] 'git <command> [<revision>...] -- [<file>...]'

it looks like there is a similar problem on jenkins:

https://github.com/jenkins-x/jx/issues/5534

does it include teamcity?  This problem appears on each branch except master but the build.sh script stays the same. I have run out of ideas on how to solve it. Would be happy to hear back from you,

Kind regards,

K.
