Retrofit 2 RequestBody JsonArray

How can I put a JSONArray into a RequestBody without a runtime exception being thrown?

@Multipart 
@POST("/call_method")
Call<MyResponse> callMethod(@Part("token")RequestBody token,@Part("params")RequestBody params);

I need to put JSONArray into params. What I currently do:

callMethod(RequestBody.create(MediaType.parse("text/plain"), token),
           RequestBody.create(MediaType.parse("text/plain"), jsonArrayParams));

But when I execute this method, I'll get a runtime exception: 

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line

And very intersting: The request is executed (check via CharlesProxy) but I can't see it result due to the runtime exception. How can I fix this bug?

the execution is fine, your problem is in the response,

Expected BEGIN_OBJECT but was BEGIN_ARRAY

as you declared receiving an object Call<MyResponse> while you are receiving an Array

you need to change the Type in the callback as following

Call<MyResponse[]> callMethod(@Part("token")RequestBody token,@Part("params")RequestBody params);

OR

Call<List<MyResponse>> callMethod(@Part("token")RequestBody token,@Part("params")RequestBody params);
