Bug description

we have this action running in two separate repos (1)(2), and in both v6 now gets stuck on:

Error: Repository is in detached HEAD state. Please make sure you check out a branch. Adjust the input accordingly.

i understand this is a feature not a bug (introduced in #357), but we never had problems before with the old version. what are we doing wrong?

Steps to reproduce

eg https://github.com/BalancerMaxis/bal_tools/actions/runs/15573050946/job/43863386559?pr=105 or https://github.com/BalancerMaxis/multisig-ops/actions/runs/15573089744/job/43852869376?pr=2113
