Content-Type being set to binary/octet-stream

When making a request for an M4A file, we have been seeing the Content-Type being set to binary/octet-stream instead of audio/mp4. Is there a way to add additional mime types to cloudflare? Is there a reason this mime type isn’t supported? This is causing issues with some customer content.

We are using workers and page rules for other mp4 content and other types of content just fine. Cloudflare returns them properly with no issues.

Cloudflare proxies the Content-Type header, it doesn’t change it. Either your worker or the origin is returning that content type.

I’ve reviewed the response from origin and content-type is being set to binary/octet-stream. Will follow-up with them. Thanks!
