Assignee drop down picker Jira error


When any users on JIRA (server) including admin, try to use the assignee picker error displayed. Can click on assignee me this works and typing in a name works?


The JIRA Server was contacted but has returned an error response. We are unsure of the result of this operation.

Hey Kevin!

Hilariously, I ran into this exact issue on one of my instances today.

What it turned out to be was the name in the Assignee field was not the actual user object; instead it was some value that this pluginhad inserted into the field without validation.  The fix for us was to clear the field manually, (you can probably use a post function to do this), then try and figure out why the plugin was inserting bad data in the field.  Haven't figured out that part yet.

Good luck!

We needed to change the usernames of all users to match with other system logins.

After doing so, and reindexing the database, we had this error appear whenever trying to select a person to assign an issue to (clicking the down arrow at the right of the field).

We went to the addons configuration screen and turned on safe mode (disabling user addons) - this did not solve the issue.

Any suggestions for what else to try?
