[Bug 1507031] [NEW] Add and then delete a user, results in unexpected error on the Openstack UI

 

Public bug reported:

Here is how to reproduce it:

1. Install an Ubuntu Openstack on a VM.

2. Login to the horizon for that VM.

3. Add a new user role using the following command using CLI:
keystone user-role-add --user <AN_EXISTING_USER> --tenant <AN_EXISTING_TENANT> --role < MEMBER_ROLE>

4. Remove the user role, using the following command:
keystone user-role-remove --user <SAME_EXISTING_USER> --tenant <SAME_EXISTING_TENANT>  --role < SAME_MEMBER_ROLE>

5. Refresh the horizon, UI redirects to an error message page, with the following error message:
"Something went wrong! An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator."


A screenshot of the UI is attached.

Please note that refreshing the page does not resolve the issue.
However, either clearing the browser's cookies/history for that session
or opening the horizon on an "Incognito" mode may resolve the issue.
