Prevent Files from being converted to JSON in the request?

[Leviathan91]

Using @hey-api/openapi-ts,
when I try to use the generated import methods for an upload excel file function, I can see in the network tab that the request content-length is always 2, I assume that is because it tries to json the file attached in the method invocation, which it cant on a File, so it returns {}.

When I use my swagger-api directly, a file import works. Same if in my frontend instead of calling the generated import method, I use a native fetch call. So I know that the library somehow transforms my request.
But I have found no way how to stop that transformation, there are transform options, but only for dates. And If i enable transformers so i can access them on my methods, all transformers are response transformers, but I need request transformers, since I am targetting the upload request, not it's reponse.

Hi @Leviathan91, are you able to offer a reproducible example/OpenAPI spec?

[Leviathan91]

Not right now, I'll see if I can pull together something on the weekend. Just the OpenAPI spec would be enough, or should I fork one of your stackblitzes and show the whole process?

If you've got a running API I could hit, spec would be enough. I need to be able to reproduce the issue

Yeah I'll try to build something, can't provide the real one.
