I think this can be simplified slightly?

We're seeing an issue and it seems related to this change, but I'd like to verify. So the behavior we're seeing is:

• User makes a new dashboard
• Clicks Draft button
• (sometimes) is prompted to log in
• (sometimes) is not prompted to log in
• (always) gets a 401 error with the message {"message":"Access is Denied","severity":"danger"}

Would this be fixed after we get this change?

Gengle ping, can @dpgaspar or anyone else chime in?

UPDATE: this issue went away when we upgraded to version 0.36
