"Error: URL.pathname not implemented signalr" - @microsoft/signalr V8.0.0 on React-Native 0.72.7

### Describe the bug

Hi,

I updated the @microsoft/signalr package on my react-native app from V7.0.12 to V8.0.0 and it stopped working after the update.
The connection is failing when firing the start() method.
The error: "Error: URL.pathname not implemented signalr".

This is the code (which works fine with V7.0.12):

let hubConnection = new HubConnectionBuilder()
.withUrl(`${CONFIG.MOBILE_SERVER_BASE_URL}/${hubName}`, { transport: HttpTransportType.WebSockets })
.build();

hubConnection.start()
.then(() => {
...
})
.catch((error) => {
...
});

Thanks
