How can I see the reason for a transition failure?

Teddy Funger

When I create a branch through JIRA, it should transition the issue to the next state. When I create the branch, in the workflow transition edit page, it says there was a transition error on the issue, and it gives me what looks like an id in the form of "1423487962418". Is there a place I can see an error message?

Since you are on cloud, you will have to request for logs from Atlassian.

I would start by looking at the workflow conditions/validators/post functions just to make sure they don't reference an invalid entity like a deleted custom field. And then request for logs if I can't find anything suspicious.
