'Debugger.getScriptSource' method is not working

[lifeasageek]

While the event "Debugger.scriptParsed" is correctly handled, getScriptSource() always returns "undefined" value.

I guess I was invoking the method (getScriptSource()) in a wrong way as inspector.js of blink is calling the getScriptSource() via DebuggerAgent, which seems to be the wrapper of Debugger interface.

var spawn=require('child_process').spawn;
var Chrome = require('chrome-remote-interface');
var initWaitTime = 2000;
var ChromePath = "/usr/bin/chromium-browser";

function runChrome(extensionDir) {
var args = [];
args.push("--remote-debugging-port=9222");
args.push("--user-data-dir=remote-profile");
args.push("-no-default-browser-check");
spawn(ChromePath, args)
};

function runChromeDebugger(urlToVisit) {
console.log("runChromeDebugger");
options = {};
Chrome(options, function (chrome) {
with (chrome) {
on('Debugger.scriptParsed', function (msg) {
console.log("==================================");
console.log(JSON.stringify(msg));
console.log("scriptParsed scriptId: " + msg.scriptId); // scriptId is correctly returned
var ssrc = chrome.Debugger.getScriptSource({'scriptId':msg.scriptId});
console.log("scriptSource :" + ssrc); // bug? always undefined
});
Page.enable();
Debugger.enable();
Page.navigate({'url': urlToVisit});
console.log("[*] opened [" + urlToVisit + "]");
}
}).on('error', function () {
console.error('Cannot connect to Chrome');
});
}

if (require.main == module) {
runChrome("/home/blee/project/chrome-extension-integrity/sample/buzzdoc");
var urlToVisit = "http://google.com"
setTimeout(function() {runChromeDebugger(urlToVisit)}, initWaitTime);
}

Oh.. I figured this out. Gotta get the results back using the callback function like below. Thanks for the great code!

        on('Debugger.scriptParsed', function (msg) {
            chrome.Debugger.getScriptSource(
                {'scriptId':msg.scriptId},
                function (err, msg) {
                    if (err) return;
                    console.log("script : " + JSON.stringify(msg));
                });
        });
