Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $

Issue Summary

Getting the error:

Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $

Here's my code:

public void onCreate(Bundle savedInstanceState) {
        Log.i(TAG, "onCreate");
        super.onCreate(savedInstanceState);
        final Video video = VideoPlayActivity.video;

        TestApp d = new TestApp();
        d.onCreate();
        mApiClient = d.getmApiClient();

        String uri = video.getVideoUri().toString();
        mApiClient.getInstance().fetchNetworkContent(uri, new ModelCallback<Video>(Video.class) {
            @Override
            public void success(Video video) {
                Log.i(TAG, "get success.");
                // use the video
            }

            @Override
            public void failure(VimeoError error) {
                Log.i(TAG, error.getErrorMessage());
                // voice the error
            }
        });
}

And these are the important methods in TestApp:

public class TestApp extends Application {
@Override
    public void onCreate() {
        super.onCreate();
        Log.i(TAG, "onCreate");

        sContext = this;

        Configuration.Builder configBuilder = getClientIdAndClientSecretBuilder();
        VimeoClient.initialize(configBuilder.build());
        mApiClient = VimeoClient.getInstance();
    }
    
    public Configuration.Builder getClientIdAndClientSecretBuilder() {
        String clientId = "dc62dc72e8c7cf4d0b7bb025d41e2a7649ddc0a4";
        String clientSecret = "SRbzt7mLfbA0l5aEV8lXINE54nRGkSp8S2i+wOp9paOqQsEKkwC5MtdwFPHiVqX7DTCooPVWAxPVjG8/pjjPbl+7LNTXTuSDit1oZGtCjkBYFqahb95J4pAHzEumdNhs";
        return new Configuration.Builder(clientId, clientSecret, SCOPE);
    }
}

Start at fetchNetworkContent and the ModelCallback path shown in the report, then trace where the response is parsed and where the JsonReader error is produced. Compare the received response with the expected JSON and determine the intended handling for malformed or non-JSON content; done means the failure is explained and covered by an appropriate regression test.
