Hi folks,
I'm out of ideas on what could be causing this problem.
Long story short, teams migrated from Bitbucket to Github.
Team was used to create release branches from Jira named like
release/1.49
In Bitbucket, branches like this could be created just fine from Jira. Now with Github, a strange error appears: "The issue key does not match the selected issue".

Interestingly enough, it does not seem to be a problem in github, as a branch can be created with this name there.

I don't recall seeing any validations set at Jira side specifically for the Github integration. Am I missing something?
