window.fetch(input, [init])

Fetches a resource from the network.

Returns: Promise<Response> Promise that resolves to a Response object.
Throws:

TypeError If init.body is set and init.method is either "GET" or "HEAD".
TypeError If either network error or network time-out occurs after a http request is made.
TypeError If there is a failure in reading files in FormData during posting FormData. In order to leverage fetch, update the manifest.json with the network.domains permission shown below. Example:

{
  "permissions": {
      "network": {
          "domains": [
              "https://www.adobe.com",
              "https://*.adobeprerelease.com",
              "wss://*.myplugin.com"
          ]
      }
  }
}

Limitation: From UXP v7.4.0 onwards permissions.network.domains does not support WildCards in top-level domains. Example:

"domains": [ "https://www.adobe.*", "https://www.*" ]
