I have an endpoint that doesn't response with JSON, instead it responses with some headers and with file bytes in response body. I would like to add that spec to my Swagger docs, but haven't found a clear solution. Appreciated. Thanks

Read the part regarding response headers.

I don't know how you check the document, but it do have a section on response headers. https://github.com/fastify/fastify-swagger#response-headers

Please provide a minimal reproducible code if that doesn't work.
