"Invalid user id" when adding panel in dev rig extension views

I’ve created the Hello World project without any problems as far as i can see but when i go into the extension views tab and try to add a panel it says my user id is invalid. Right now i’m using the developer rig user but should i use something else? Do i need to update/config the user somehow?

if you are using the (legacy?) web based dev rig, you’ll probably see a failed call to /helix/users that returns a 401 if you look at the requests being made in dev tools. I don’t know what caused the authorization token to get stale, but I noticed that if I logged out of the dev rig and back in (using my twitch dev account), I was able to run the type of extension view (panel, component, etc.) I needed. Hope this helps somebody.
