Receive 404 when trying to log error message to ionic Pro monitoring

We followed the guide on ‘https://ionicframework.com/docs/pro/basics/getting-started/#pro-client-setup’ everything builds and runs fine but when we try to log an exception we get a 404. The url used to log is https://api.ionicjs.com/monitoring/APP_ID_FROM_DASHBOARD/u

The message we receive is:

{"error": {"link": null, "message": "404 Not Found: The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.", "type": "NotFound"}, "meta": {"status": 404, "request_id": null, "version": "2.0.0-beta.0"}}

Anyone knows what is wrong/what we need to do to fix this
