Overview

Admins may run into issues where they cannot push groups to Google Workspace and receive the following error:

Failed on xx-xx-20xx xx:xx:xx UTC: Unable to update Group Push mapping target App group xxx.

Applies To
  • Google Workspace
  • Group Push
Cause
This error appears when there is a duplicate entry for key externalIdAndInstanceKey.

Example error: 

Could not execute statement; SQL [n/a]; constraint [externalIdAndInstanceKey]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement. 
Solution
  1. Ensure that no changes have been made on the application side and the group side.
  2. Unlink Push Group with the option: Leave the group in the target app.
  3. Refresh the App Group and push the group again.
  4. If pushing the group gets an error: Pushing groups that have the same name and AppInstance is unsupported, then delete the cloned groups with API: DELETE/api/v1/groups/${groupId}.
  5. Push the group again.
