Websocket Error

Hi there! I followed “Realtime Data Update with NodeJS and WebSockets” for live data refresh.

Now, it works perfectly inside Wappler, it shows the data update in realtime when I add a record from another page, but when I load it in the browser it gives some errors.

I’m using Wappler 4.0.1 with Nodejs + Postgres + Docker Desktop

Please bear with me as I don’t have any experience with this :grin:.
Can anyone explain me what to do / change / configure? Thanks in advance!
