Conexión de Javascript a WebSocket en localhost y google chrome: conexión fallida (trabajando en cartero)

Estoy intentando conectarme a ws://localhost:8080 dentro de mi aplicación React. El navegador web que estoy usando es Google Chrome.

Puedo conectarme al websocket en Postman, pero en Google Chrome recibo este error: WebSocket connection to 'ws://localhost:8080/tables' failed: .

El código fuente de la aplicación es:

 const ws = new WebSocket('ws://localhost:8080/tables'); ws.onmessage = function message(data: any) { console.log('received: %s', data); };

¿Qué me estoy equivocando?
