Issue Summary

• When trying to delete the owner of a Personal workspace, an invalid error message is presented.
• NOTE: this also displays if you attempt to delete the only user present in groups on the workspace.
  For example - workspace has two users, userA is the owner and they are not in any groups, userB is an admin - deleting userB causes the error

Steps to Reproduce

1. Access a Personal Workspace with an account that is workspace admin but not the owner of the personal workspace (or the only group member - see above)
2. Navigate to Workspace Settings > User Directory
3. Try to remove the user

Expected Results

An error message indicating that removing access from the owner/only group member of a personal workspace is not possible

Actual Results

The below invalid error message is presented : 

Error

Unexpected token '<', "<!DOCTYPE "... is not valid JSON

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
