I am getting CORS errors in S3 console, is this a bug with AWS S3?


I don't have an account to fill out a tech support ticket, but this isn't tech support. It feels like a bug:

Access to XMLHttpRequest at '' from origin '' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

A lot of these errors for all of my buckets. On the main list of buckets I am getting all 400 responses from the Access column for all buckets. It shows 'Unknown Error':

Request URL:
Request Method: POST
Status Code: 400 
Referrer Policy: no-referrer-when-downgrade
