Hi,
Just wondering if anyone can shed some light into an error I'm seeing. This
is on GoCD version 16.7.0, build 3819.
The below errors happen when I try to trigger a pipeline (to build a rails
app). The pipeline doesn't start at all.
Modification check failed for material: URL: ssh://git@code.<hidden by
Hans>.git, Branch: master [Sep-24 02:41:19]
Error performing command: --- Command --- git rev-parse --abbrev-ref HEAD
--- Environment --- {GIT_ALLOW_PROTOCOL=http:https:ssh:git:file:rsync} ---
INPUT ---- --OUTPUT --- HEAD --- ERROR --- STDERR: fatal: ambiguous
argument 'HEAD': unknown revision or path not in the working tree. STDERR:

Any idea what causes this? Is the above 'modification check' done on the
GoCD server or the agent?
I've noticed that the pipeline starts fine immediately after I change the
'Destination Directory' in the Materials setting, just for one time. But
the next time I try to kick it off, it wont start, and the same error is
shown. However if I change the Destination Dir again (say to a blank), then
it starts fine, for one time.
The git repo is a bitbucket repo, and the branch is 'master'. It connects
fine, as shown here:

Also, I've enabled 'Clean Working Directory' for each stage, however this
didn't help (I saw this as a recommendation when I searched for this error
in this forum):
Thanks,
Hans
