If you see a <POST> request to <https://api.rollbar.com/api/1/item/> throwing a 429 error in your console, you can ignore it! We use Rollbar internally to track sdk errors.
You can also ignore any api calls to <user/login/email/status> that return a 401 error - that's a poller that runs in the background and checks if the user has clicked the Magic Link.
Ignorable 429 and 401 errors in the console
