I just generated a new web part using the Yeoman generator for SPFx 1.4.1, and am debugging it in the hosted workbench. We are using SP2016, On Prem.
I am seeing console logging that looks like this:
Failed to load resource: the server responded with a status of 403 (Forbidden) [http://our-onprem-sharepoint.com/_layouts/15/WsaUpload.ashx]
Any suggestions on
- the source of these requests? (I didn't write them...)
- how I can make them stop?
