onUpdate is not calling

[ravirupareliya]

I have deployed it on firebase hosting. While testing it with actions simulator, it is calling conversation but does not call onUpdate callback of ImmersiveResponse.

 conv.ask(`Ok, I changed my color to ${color}. What else?`);
 conv.ask(new ImmersiveResponse({
     state: {
         tint: tints[color],
     },
 }));

from above code I am able to see response Ok, I changed my color to Red. What else? but onUpdate log is not printed on firebase functions console.

code snippet for callback

// register assistant canvas callbacks
const callbacks = {
    onUpdate(state) {
        console.log('onUpdate', JSON.stringify(state));
        if ('tint' in state) {
            sprite.tint = state.tint;
        }
  },
};
assistantCanvas.ready(callbacks);

onUpdate would not be called in your Firebase Function at all. It would appear locally in your web surface and be logged in your local devtools.
