Body parameters cannot be used with shape parameters. - Recognize client with json headers and data

I have a FeignClient like this

@RequestLine("POST /enroll")
@Headers({ "header1: {header1}", "header2: {header2}", "Content-Type: application/json" })
ResponseDto enroll(@Param("header1") String header1,@Param("header1") String header1, RequestDto requestDto)throws MyCustomException;

`I am not using spring cloud netflix. But I keep getting the exception.

Caused by: java.lang.IllegalStateException: Body parameters cannot be used with form parameters.
at feign.Util.checkState(Util.java:128)
at feign.Contract$BaseContract.parseAndValidateMetadata(Contract.java:112)

at feign.ReflectiveFeign.newInstance(ReflectiveFeign.java:53)
at feign.Feign$Builder.target(Feign.java:209)
at feign.Feign$Builder.target(Feign.java:205)

I am creating my client this way.

return Feign.builder()
        .encoder(new JacksonEncoder())
        .decoder(new JacksonDecoder())
        .logger(new Slf4jLogger())
        .logLevel(Logger.Level.FULL)
        .target(RegularFeignClient.class, url);

Wow, this is tricky. Here's the order of the parameters.

@RequestLine("POST /enroll")
@Headers({ "header1: {header1}", "header2: {header2}", "Content-Type: application/json" })
ResponseDto enroll(RequestDto requestDto, @Param("header1") String header1,@Param("header1") String header1)throws MyCustomException;


It works!!!

Thanks to my senior developer. He found it.
