My current dev environment is destroyed in a number of interesting ways for unrelated reasons so I can't get the actual error output to show, but I just ran into this. The error happens here:
and is caused by assuming that you'll have other repositories cloned, when none are specified, you aren't returned something iterable:
As a workaround, editing + saving the step should populate this with an empty array. But we can be a little more defensive in the actual implementation.
Specifically, I think this was only for steps created prior to the introduction of the "Other Working Copies" field. New ones should work OK without specifying additional working copies.
I did do at least this to try to get this to disappear:
I don't think it populates the value as [], which is what I was expecting. Maybe that's what customfield tries to do, but harbormaster step values clobber it somewhere?
Yeah it's busted by default including newly created steps
