CDP COmmands Not working

[phaneendra yandrapragada]

I have opened a remote debugging port on the Chrome. With PostMan I have connected to the CDP websocket and sending some commads but most of the commands except Target domain are throwing with message like

Request :

{ "id":1, "method":"Network.enable", "params":{ "maxTotalBufferSize" :4096 } }

Resposne :

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

I have tried commands of multiple domanis like Page,Network etc but all are throwing error like respective commands not found.I have tried adding sessionId also like but still not working nd throwing session id is invalid.

{ "id":1, "sessionId":<sessionid received from Target Attachment command> "method":"Network.enable", "params":{ "maxTotalBufferSize" :4096 }}

Why it is not working? Are there any settings I have missed?

I assume you're sending these to the "browser" WebSocket url?
The browser WebSocket looks like (for example): `ws://127.0.0.1:9222/devtools/browser/<identifier>`, you'll likely want to create a target first and then get the "page" WebSocket URL from `http://127.0.0.1:9222/json/list` which looks like `ws://127.0.0.1:9222/devtools/page/<identifier>`.
