Unable to initialize livequery connect

[shankarnat]

https://github.com/shankarnat/ParseLive-Query - is my code. I had tried to do the same example as given in your repository.
Also, I used this backend for just Parse to Insert and read; it worked.

This is the example of the code with just Parse (and not live query against the same backend_ https://github.com/shankarnat/ParseExample and this works and ingests the data.
Now, I confused as to what I am missing.
I have updated the index.js file to ensure the API call and livequery parameters are added as per - this https://github.com/ParsePlatform/parse-server-example/blob/master/index.js and the websocket for the backend is also enabled.
Can you help?
