Issue Summary

When adding agents as admins to Data Manager you might get "Something went wrong, please contact support"

Steps to Reproduce

1. Add agent as admin or adapter admin to Data Manager

Expected Results

The user should be added successfully to the role

Actual Results

Some users get intermittent "Something went wrong" popup

We can see that from the endpoint "v1/config/perms/role-assignment" we get a 400 response code and the following response payload:

{
  "errorMessages": [
    "User or Group could not be assigned to Role."
  ],
  "errors": {}
} 

Workaround

You must remove every inactive user that is already associated with an Asset Data Manager Role (Data Manager admin, Adapters admin, Dashboards viewer, Dashboards editor).
