Error: No content to map to Object due to end of inputBitbucket server and Jira Cloud are connected via Application links as mentioned on this page: Link Bitbucket with Jira and the application link is using OAuth.
Cause
This issue is caused by the bug on the Jira side JSWSERVER-14908. This bug reports a similar error when the app link has been established between Jira and Bitbucket and OAuth user impersonation has been disabled.
Solution
Delete and recreate the Application Link. You may need to delete the link separately on each side before recreating it. After recreating the application link, the users might have to authorize themselves on Jira and Bitbucket.
