Quarkus @MultipartForm throws 415

I am trying to upload a file using quarkus-resteasy-reactive-jackson. Following different tutorials I seem to have everything setup as needed, but when I try to upload a file I get a 415 response code.

@Path("/companies/{companyId}/induction")
@Produces(MediaType.APPLICATION_JSON)
public class InductionController {

    @Inject
    InductionService service;

    @POST
    @Path("/{inductionId}")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(
            @PathParam("inductionId") Long inductionId,
            @PathParam("companyId") Long companyId,
            @MultipartForm InductionFile uploadedFile
    ) {
        String fileLocation = "/uploads/" + companyId + "/" + StorageLocation.INDUCTION.getProperty() + "/" + inductionId;
//        InductionEntity induction = service.saveFile(uploadedFile, inductionId, fileLocation);
        return Response.ok().build();
    }
}

public class InductionFile {

    @FormParam("inductionFile")
    @PartType(MediaType.APPLICATION_OCTET_STREAM)
    public byte[] data;
}

This is my setup and it looks right to me, but it obviously isn't. Can anyone shed any light on this for me?
