Answer 1

You have an misspellings in constuctor, thus this.web3... line never run. Correct one is constructor.

In your code there is another problem, when you use websocket, you dont need to use HttpProvider just pass websocket url to web3:

this.web3 = new Web3('wss://mainnet.infura.io/ws/v3/' + projectId);
