Serverless tutorial bug with CORS config

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?

Thanks

Ok, I can narrow the problem down. It is happening for me only in the “new” version of the S3 Bucket UI. If I switch to the old version, I can enter the CORS configuration with no difficulty.

Oh that’s super weird. Glad you figured out the issue.
