Cannot deploy another branch than main or master for Scalingo

[MatBdry]

Hi,

I'm trying to deploy my application to Scalingo through GitLab CI, but I'm getting the following error:

Cannot push on non-master or non-main branch.

I don't think this should be an issue, since it's possible to deploy from the console by specifying the target branch (for example):

git push scalingo feature/scalingo:main

Do you have any idea what might be causing this?

Thanks a lot!
