In the “allowed references” for the startWebRequest one of the listed api urls is api.openweathermap.org. But the api at openweathermap.org has changed, and all the urls start with ‘samples’ instead of ‘api’. This is really inconvenient since openweathermap seems to be the only weather api that is available without getting an api key. This should be updated.
We agree @jim.stewart and are working on updating the documentation. Thanks for reporting!
