Issue Summary

Intermittently we have Jira users that have enough permissions and privileges throw unexpected error message below when trying to use a Jira user picker (e.g. assignee)

User xxx was not found in the system

Environment

Only some instances are impacted and this ocurs only on Old Issue View that have a profile related feature applied.

Steps to Reproduce

1. Login to Jira then access any issue and access any Jira User Picker field. 
2. Type in Full Name at User Picker and pressing enter.
3. On purpose the drop down list value was not selected.

Expected Results

User can be picked and issue can be saved correctly

Logs - User value is passed correctly when selected from the dropdown item, it updates to

<input type="hidden" id="hidden-customfield_10028" name="customfield_10028" value="123xxxxxxAAIDxxxxxxxxxx123">

Actual Results

Error is thrown as above and the assumption is that user cannot be picked as value for the field

As the Full name for example type “Firstname Lastname” into the field, it will look like

<input type="hidden" id="hidden-customfield_10028" name="customfield_10028" value="Firstname Lastname">
 

Notes

NA

Workaround

Select the correct user from the dropdown list using the mouse, instead of directly hitting enter
