Auto WebP activated, "Content-Type: image/webp" returned, but still it's JPG encoded

[anibarro]

Hi,

I have deployed the solution with auto-WebP activated, but it's not working.

The "Accept" header is being sent with the webp type included and the server is responding with "Content-Type: image/webp" (if I try to save the image, the browser saves it with webp extension).

The problem is that the image is exactly the original jpg file, it's not being converted to WebP. If I add a WebP filter ("filters:format(webp)"), then it works as expected.

How could I debug this and what could be the reason?

Thanks!

Thanks for reporting the issue. I have added this to our list of backlog items while working on fix.

Thanks for checking, can you then confirm that this is actually not working?
I didn't mark it as a bug because it's strange that a feature that so many people is using doesn't work

I can reproduce this issue. I do see the size difference in the resulting image with AutoWebP enabled vs filters:format(webp). So I have assigned this to our team for further debugging.

Thanks a lot!
