Cloudfront serves as text/plain files copied with aws s3 cp index.html s3://bucket/index.html --content-type text/html --cache-control max-age=30

I am facing this issue for some time now, it appears to be a delta between the copy and the actual set of content-type.

If one visits the domain associated with the bucket, in between that delta, then cloud front will server index.html as a text/plain and there would be no way to fix it without requesting cache invalidation + browser forced refresh + restart of browser.

Is there a way to ensure the proper content-type is set, prior to cloud-front accessing the object ?
