How can I connect to polygon.io web socket via Alpaca?

Question

Whenever I try to use the command:

wscat -c wss://alpaca.socket.polygon.io/stocks

I get the following error message displayed:

error: self-signed certificate

I'm using PyCharm on my 2022 MacBook Air. Can anyone help here?

• tried this what I found online:

  npm config set strict-ssl=false

  did not work.
