I am getting the same error. Although I'm not using REST API. I'm using Swift.
Based on a few other replies on other similar messages, we are not alone.
My code was working fine last night. Tried today after making a few changes and I keep getting error 401. I reverted my new changes and still get the error.
I have up-to-date provisioning profile and certificates, and have WeatherKit correctly integrated (as of yesterday at least).
I went back to Apple's FlightPlanner project and even that doesn't work anymore. I made a very stripped down weatherkit program and can't get that to work either.
Here's my error message from FlightPlanner in case others are experiencing it too. Apple, please help.
