[🐛 Bug]: BiDi is not working (Firefox/Chrome)

[DashwoodIce9]

What happened?

Hi, I am trying to intercept and modify network requests using WebDriver BiDi API. I have tried with Firefox and Chrome on MacOS and Linux and in all cases it has failed to work for me. I am getting an error like the following. The prakhar.App.main(App.java:xx) line in the stacktrace corresponds to the Network network = new Network(webDriver) line in the code examples shared below.

With Firefox -

// On MacOS

How can we reproduce the issue?

Hello! Thank you for sharing the details. Please ensure that the "websocketurl" capability is set to true.

Example:

  FirefoxOptions options = new FirefoxOptions();
  options.setCapability("webSocketUrl", true);

The code example shared does not have this capability set. Hence, you are getting the error mentioned.
Please refer to code examples here.

I've seen a few issues raised due to the same problem. I pushed a small change that improved the error message.

[pujagani]

Ahh okay. Thank you, Diego!
