Both Claude and ChatGPT 4o seem to agree on:

defp upload_css_to_cloud(source, dest) do
  bucket()
  |> ExAws.S3.put_object(
       dest,
       File.read!(source),
       headers: [{"Content-Type", "text/css"}]
     )
  |> ExAws.request()
end

Curious if that works.

I doesn’t unfortunately, both Claude and ChatGPT offered multiple solutions, but no matter which one I try, CSS file always ends up having application/octet-stream as a content type.

Can you try to see what Tigris returns?

“text/css” ?
