Unable to load Renderable when trying to implement ar core

Question

Why am i getting this error when trying to create an ar app?

Unable to load Renderable registryId='android.resource://com.nevco.ar/raw/cat'
    java.util.concurrent.CompletionException: java.lang.AssertionError: No RCB file at uri: android.resource://com.nevco.ar/raw/cat

I am folliwng this tutorial to create a simple ar app, but everytime i launch my app i keep getting this error. I am not sure what to do to fix this. Some help would be grealty appreciated. I attached the link to the tutorial. https://www.androidauthority.com/google-arcore-972579/

public class MainActivity extends AppCompatActivity {
    private static final String TAG = MainActivity.class.getSimpleName();
    private static final double MIN_OPENGL_VERSION = 3.0;

    private ModelRenderable dinoRenderable;

You have to first create a node and add renderable of the model in it then attach it to the arFragment. You just used the renderable directly without creating a node. There you are getting the error. Check the below code addNodeToScene() method.

Try the following code,

package com.example.arcorefirst;

import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.MotionEvent;
import android.widget.Toast;

import com.google.ar.core.Anchor;
import com.google.ar.core.HitResult;
import com.google.ar.core.Plane;
import com.google.ar.sceneform.AnchorNode;
import com.google.ar.sceneform.rendering.ModelRenderable;
import com.google.ar.sceneform.rendering.Renderable;
import com.google.ar.sceneform.ux.ArFragment;
import com.google.ar.sceneform.ux.TransformableNode;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = MainActivity.class.getSimpleName();
    private static final double MIN_OPENGL_VERSION = 3.0;

    ArFragment arFragment;
    ModelRenderable lampPostRenderable;
    private Uri selectedObject;

    @Override
    @SuppressWarnings({"AndroidApiChecker", "FutureReturnValueIgnored"})
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        arFragment = (ArFragment) getSupportFragmentManager().findFragmentById(R.id.ux_fragment);
        arFragment.setOnTapArPlaneListener(
                (HitResult hitresult, Plane plane, MotionEvent motionevent) -> {
                    if (plane.getType() != Plane.Type.HORIZONTAL_UPWARD_FACING)
                        return;

                    Anchor anchor = hitresult.createAnchor();
                    placeObject(arFragment, anchor, R.raw.cube);
                }
        );
    }

    private void placeObject(ArFragment arFragment, Anchor anchor, int uri) {
        ModelRenderable.builder()
            .setSource(arFragment.getContext(), uri)
            .build()
            .thenAccept(modelRenderable -> addNodeToScene(arFragment, anchor, modelRenderable))
            .exceptionally(throwable -> {
                    Toast.makeText(arFragment.getContext(), "Error:" + throwable.getMessage(), Toast.LENGTH_LONG).show();
                    return null;
                }
            );
    }

    private void addNodeToScene(ArFragment arFragment, Anchor anchor, Renderable renderable) {
        AnchorNode anchorNode = new AnchorNode(anchor);
        TransformableNode node = new TransformableNode(arFragment.getTransformationSystem());
        node.setRenderable(renderable);
        node.setParent(anchorNode);
        arFragment.getArSceneView().getScene().addChild(anchorNode);
        node.select();
    }

}
