I have a composer update error during in one of my Travis CI tests:
https://travis-ci.org/JoryHogeveen/view-admin-as/jobs/399186175
The weird thing is that it only keeps failing with this particular test. All other tests (running the same config) are working fine:
https://travis-ci.org/JoryHogeveen/view-admin-as/builds/399186171
Also, the same test for the PR build is also working fine:
https://travis-ci.org/JoryHogeveen/view-admin-as/builds/399186189
Error:
[RuntimeException]
Failed to execute git show-ref --head -d
fatal: git show-ref: bad ref HEAD (8a4672aca8db6d807905d695799ea7d83c8e5bba)
It would be awesome if anyone could help me or at least point me in the right direction.
Thanks in advance!
