This is a question about the Serverless Stack tutorial at https://serverless-stack.com/.
During the segment “Create an S3 Bucket for File Uploads”, I am configuring CORS by typing in the recommended block of XML into the editor. This XML is rejected with API response “Expected params.CORSConfiguration.CORSRules to be an Array”.
The XML is well-formed and valid, and seems to conform to the rules of CORS configuration shown in the AWS documentation link below. Is there a fix?
