Method invocation 'string' may produce 'java.lang.NullPointerException'

@Override public void onResponse(@NonNull Call call, @NonNull Response response) throws IOException { try {

                    String jsonData = response.body().string(); //NULLPOINT exception , warning //is in this line of code
                    Log.v(TAG,jsonData);
                    if (response.isSuccessful()) {
                        mCurrentWeather = getCurrentDetails(jsonData);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                updateDisplay();
                            }
                        });

                    } else {
                        alertUserAboutError();
                    }
                } catch (IOException e) {
                    Log.e(TAG, "Exception caught: ", e);
                }
                catch (JSONException e){
                    Log.e(TAG, "Exception caught: ", e);
                }
            }

Unless you have a method named string(), I'm assuming it should be toString().

String jsonData = response.body().toString();
