AWS Amplify doesn't forward headers

Question

I did deploy a nextjs application on aws amplify, everything is working well.

Now I wanted to use the accept-language header in my application, which does work when I call the cloudfront distribution domain(d2a2qapzh.cloudfront.net), but when I call the main link in amplify(https://main.d2u3plsd0.amplifyapp.com/), the accept-language header doesn't get forwarded.

Any ideas?

Amplify uses Cloudfront in background. Cloudfront plays with your headers for few reasons related to caching.

You can refer that list of headers here

I had created an issue with Amplify for similar case with ACCEPT, CONTENT_TYPE, HTTP_ACCEPT. Its still in their feature requests.
