Internal Server error while using Retrofit

Question

I am getting internal server error while executing a PUT request using Retrofit on my android app. Here is my Interface

public interface RetrofitInterface 
{
//for updating user
@PUT("users/update/{email}")
Call<Response> updateUser(@Path("email") String email,@Body User user); 
}

And Heres my class

   public void updateProfile(User user) {

private String name;
private String email;
private String city;
private int age;

private String password;
private String created_at;
private String newPassword;
private String token;

public void setName(String name) {
    this.name = name;
}

public void setEmail(String email) {
    this.email = email;
}

public void setCity(String city) {
    this.city = city;
}

public void setAge(Integer age) {
    this.age = age;
}

public void setPassword(String password) {
    this.password = password;
}

public String getName() {
    return name;
}

public String getEmail() {
    return email;
}

public String getCity()
{
    return city;
}

public Integer getAge() {
    return age;
}

public String getCreated_at() {
    return created_at;
}

public void setNewPassword(String newPassword) {
    this.newPassword = newPassword;
}

public void setToken(String token) {
    this.token = token;
}

}

I am putting the name,age and city from three textViews as follwing creating a new User object

 User muser = new User();
    muser.setName(nameText.getText().toString());
    muser.setAge(Integer.parseInt(ageText.getText().toString()));
    muser.setCity(cityText.getText().toString());

    // user.setEmail(mEmail);
    updateProfile(muser);

And this is the function I am using to update the user profile

   public void updateProfile(User user) {

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("https://fitnessrace.herokuapp.com/")
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);

    Call<Response> call = retrofitInterface.updateUser(mEmail,user);
    //
    call.enqueue(new Callback<Response>()
    {
        @Override
        public void onResponse(Call<Response> call, retrofit2.Response<Response> response)
        {

            if (response.isSuccessful())
            {

                Response responseBody = response.body();
                Log.d("success", response.toString());
                Log.d("success2", responseBody.toString());
            }
            else
            {

                ResponseBody errorBody = response.errorBody();

                // Gson gson = new Gson();
                Gson gson = new GsonBuilder().create();

                try
                {
                    Log.d("error1", errorBody.toString());
                    //Response response1 = gson.fromJson(errorBody);

                }
                catch (Exception e)
                {
                    e.printStackTrace();
                    Log.d("error2", e.toString());
                }
            }
        }

        @Override
        public void onFailure(Call<Response> call, Throwable t)
        {
            Log.d(TAG, "onFailure: "+t.getLocalizedMessage());
        }
    });

From postman I put the follwing and it works postman put request

My server is a node.js server which has the definition for updateUser() function. But it is not working from android. What am I missing?

Answer 1

You have put json data to your server and in postman you have used application/x-www-form-urlencoded content type. Try to add @FormUrlEncoded before @PUT("users/update/{email}")
