Platform Notice: Cloud Only - This article only applies to Atlassian apps on the cloud platform.
Summary
When attempting to assign tickets to an agent in Jira Service Management, users may encounter the error message 'Issue could not be updated.'
Diagnosis
Issue could not be updated
The 'assignee' field of <issue_key> could not be updated. User '<User ID>' cannot be assigned issues."
Cause
The "Issue could not be updated / user cannot be assigned issues" error means the target agent is missing something.
To be assigned issues, an agent needs a Jira Service Management license plus the Assignable User and Service Project Agent permissions; to assign to others, they also need the Assign Issues permission.
Solution
Check for a Jira Service Management license
Go to Settings > User management
Select a user on the Users page
Under Groups, confirm the user has a Jira Service Management License
Check for Permissions in the service project
Navigate to the affected space
Go to Space Settings > Permissions
Ensure the affected user has the Assign Issue and Assignable User permissions
If not, select Actions > Edit permissions
For both permissions, select the Update link
In the Update permission dialog, choose who to grant the permission to and select Update
After granting the license/permissions, retry assigning a ticket to the agent to confirm the error is cleared.
