Getting unexpected JDWP: 103 error while trying to upload an image using a modification to an api Android server?

Question

I get the following error message 103 when I try to upload an image on the api server using the multipart modification, the api receives the api token, "_method": "PUT" and the image URL as parameters, when receiving the response it receives full JSON, but with the previous link or link by default, the currently selected image does not load, everything else is optional, any help will be appreciated, the code is listed below.

The main method is POST, but "_method": the "PUT" parameter allows you to upload an image, without _method it becomes a POST message, and every other parameter becomes mandatory, check the image.

com.sun.jdi.InternalException: Unexpected JDWP error: 103

Interface:

public interface UserSignUpClient {

@POST("account")
Call<AuthenticationAccountCreationResponse> createAccount(@Body UserSignUp userSignUp);

@Multipart
@PUT("account")
Call<UserInfo> postImage(@Header("Authorization") String headerValue, @PartMap Map<String, String> map, @PartMap Map<String, File> imageMap, @Part MultipartBody.Part image);

@FormUrlEncoded
@POST("account")
Call<UserInfo> updateUser(@Header("Authorization") String headerValue, @FieldMap Map<String, String> map);
}

Retrofit Builder Class:

public class RestClient {

private UserSignInClient userSignInClient;
private UserSignUpClient userSignUpClient;
private UserInfoClient userInfoClient;

public RestClient(String baseUrlLink){

    Retrofit retrofit = new Retrofit.Builder()

I think your problem is that you forgot to add an adapter to call for the modified object. In your class, RestClientyou should put something like this:

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(baseUrlLink)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .build();

Also you need to add this dependency inside build.gradle:

compile "com.squareup.retrofit2:adapter-rxjava2:2.3.0"

Hope this helps.

Greetings.
