Could not create converter for java.io.InputStream in Quarkus with Reasteasy-Reactive and JAX-RS

Question

I have the following endpoint

@POST
@Path("/images")
@Consumes("multipart/form-data")
@Produces("application/json")
fun upload(@FormParam(value = "file") fileInputStream: InputStream, @FormParam(value = "comment") comment: String): Response {
    anotherClass.save(fileInputStream, comment)
    return Response.ok().build()
}

Running a test against this endpoint returns this error:

java.lang.RuntimeException: Could not create converter for java.io.InputStream for method javax.ws.rs.core.Response upload(java.io.InputStream fileInputStream, java.lang.String altText) on class SampleClass of type FORM

Adding resteasy-multipart dependency is also not working, since it is incompatible with resteasy-reactive.

Any suggestions?
