Issue 1151822: CDP call Page.close on the non-exist session id will hang

hang.go

package main

import (
	"context"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/cdp"
	"github.com/go-rod/rod/lib/launcher"
)

func main() {
	ctx := context.Background()

	u := launcher.New().MustLaunch()

	cdp := cdp.New(u).Logger(rod.DefaultLogger).MustConnect(ctx)

	_, _ = cdp.Call(ctx, "nonexist", "Page.close", nil)
}

Actual output:

[rod] 2020/11/25 02:42:50 => #1 @nonexist Page.close null

Expected output:

[rod] 2020/11/25 02:42:50 => #1 @nonexist Page.close null
[rod] 2020/11/25 02:44:43 <= #1 error: {"code":-32601,"message":"'Page.close' wasn't found","data":""}
