Serve dynamic images via s3 with proper headers

Hi,

I have a post model with 2 database columns (post slug & s3 url) & dynamic open graph image uploaded on s3. Now if I am integrating the image to posts using open graph image tag, Facebook has some issues regarding fetching it.

Embed code:

<meta property="og:image" content="https://e91f-122-161-51-149.ngrok.io/simpleurl/HALQdIPvMhjV97wLvMmWfjRgg6KwJjsD/image/?modifications=text_subtitle~~Yoyo~~~text_title~~Hello%20World~~~image_main~~https://picsum.photos/800"/>

It shows me following error:

Image not be processed as an image because it has an invalid content type.

However I am properly 301 redirecting the above open image url to S3 Url.

Let me know whats best way to serve image from S3 with proper headers without compromising on performance. Thanks.
