RETROFIT: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $
<p>currently running into an issue after updating my gradle file of retrofit from beta2 to the current beta4. I am receiving the error shown in the title, however, this @POST method worked before but isn't currently working after the update and i cant quite put my finger on what is going wrong. Thanks in Advance for your help.</p>

<pre><code>public interface UserApi {
    String baseUrl = "some url";


    @POST("users")
    Call&lt;User&gt; postJson(@Body User user);


    class Factory{


        private static UserApi service;
        public static UserApi getInstance(){

            if(service == null){
                Retrofit retrofit = new Retrofit.Builder().addConverterFactory(GsonConverterFactory.create()).baseUrl(baseUrl).build();
                service = retrofit.create(UserApi.class);
                return service;
            }else{
                return service;
            }
        }
    }
