Hi Support,

I am developing an apps and using AWS Javascript SDK to make API to AWS S3 bucket. The problem is that I encountered a CORS issue which disallow my call to AWS S3 bucket. I have no problem to use the same code on my server to talk to S3.

============ ERROR =============
XMLHttpRequest cannot load

https://s3-ap-southeast-1.amazonaws.com/s3.demo.mydomain.com/test.json.

Response to preflight request doesn't pass access control check: No

'Access-Control-Allow-Origin' header is present on the requested

resource. Origin 'https://mydomain.freshdesk.com' is therefore not

allowed access.

Error: Network Failure
  at XMLHttpRequest.<anonymous> (aws-sdk-2.9.0.min.js?_=1488368547259:6) "NetworkingError: Network Failure
  at XMLHttpRequest.<anonymous> (https://s3-ap-southeast-1.amazonaws.com/awk-sdk/aws-sdk-2.9.0.min.js?_=1488368547259:6:31259)"

That being said, I suspect it is something to do with domain whitelisting in manifest.xml file. After did that, it returned error when validate the code. I believe the sign "-" that caused the trouble, please advise.

Validation errors:
  1. Invalid domain(s) mentioned in manifest.yml: https://s3-ap-southeast-1.amazonaws.com
