Throttling limits the rate at which your function processes requests. Creating a new function URL will result in a different URL address.

Theyre relatively easy to get rid of with the above module (if, like we do, you use IIS on Windows) but it will need to be configured almost always, as I venture to assume. A wrong protocol is specified in the url. The simplest use of fetch() takes one argument the path to the resource you want to fetch and does not directly return the JSON response body but instead returns a promise that resolves with a Response object..
