The "role not found" error in the DescribeRole function can occur if the response from the SelectGrant call does not contain any entities. This is checked by the condition if len(resp.GetEntities()) == 0, which leads to the error "role not found" ^[1].

In your test case, the SelectGrant response for the "admin" role seems to be empty, which is why the error is being logged. Here are a few things you might want to check or try:

1. Verify Role Existence: Ensure that the role you are trying to describe actually exists and is correctly set up in the system. The ListRoles function seems to list the roles correctly, so the issue might be with the grants associated with the role.

2. Check Role Grants: Verify that the role has associated grants. If a role exists but has no grants, the SelectGrant response might be empty, leading to the "role not found" error.

3. Inspect Logs for Errors: Check the server logs for any errors or warnings that might indicate why the SelectGrant call is not returning the expected entities.

4. Review Role Creation and Assignment: Ensure that roles are created and assigned correctly in your setup. There might be an issue with how roles and grants are being managed or stored.

By addressing these points, you should be able to identify the root cause of the issue and resolve the "role not found" error.
