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

This error occurs when an agent doesn't have the right permissions. 

  • To assign issues to others, agents must have Assign Issues permission in the project

    • Assignable User

    • Service Project Agent 

Finally, agents must have a Jira Service Management license.

Check for a Jira Service Management license

  1. Go to Settings > User management

  2. Select a user on the Users page

  3. Under Groups, confirm the user has a Jira Service Management License

Check for Permissions in the service project

  1. Navigate to the affected project

  2. Go to Project Settings > Permissions

  3. Ensure the affected user has the Assign Issue and Assignable User permissions

    1. If not, select Actions > Edit permissions

    2. For both permissions, select the Update link
