Here's my messages received via WebSocket. When I send this message:

{ id: 3, method: 'Network.enable' }

... it replies with:

{ id: 3, error: { code: -32601, message: "'Network.enable' wasn't found" } }

It says the same for 'Page.navigate' as well.

You need to create the session first, if you are using java / selenium the code is: devTools.createSession();

before activate that , you need to create session in the devTools you can activate with this way

    DevTools chromeDevTools = chromeDriver.getDevTools();
    chromeDevTools.createSession();

And after that you can do whatever you want
