[🐛 Bug]: dotnet Execute Script stopped working on few use cases on 4.24 and above

[omer-za]

What happened?

I’m trying to perform a request using JS with the following script.
driver.ExecuteScript(script);
it doesn’t throw any error but also doesn’t perform the request like it was before upgrading selenium version from 4.23 to 4.24

How can we reproduce the issue?

Try to run the following JS on using driver and see if a request is sent.

chrome.webRequest.onHeadersReceived.addListener(
    function(details) {
        var responseHeaders = details.responseHeaders.filter(header => header.name !== 'X-Response-Body-Signature');
        return { responseHeaders };
    },
    {
        urls: ['https://something/vendors/*'],
    },
    ['blocking', 'responseHeaders', 'extraHeaders']
);

function makeRequest (method, url) {
    return new Promise(function (resolve, reject) {
        var xhr = new XMLHttpRequest();
        xhr.open(method, url);
        xhr.addEventListener('load', function () {
            if (xhr.status >= 200 && xhr.status < 300) {
                resolve(xhr.response);
            } else {
                reject({
                    status: xhr.status,
                    statusText: xhr.statusText
                });
            }
        });
        xhr.onerror = function () {
            reject({
                status: xhr.status,
                statusText: xhr.statusText
            });
        };
        xhr.send();
    });
}
makeRequest('GET', 'https://something');

[nvborisenko]

using var driver = new ChromeDriver();
driver.ExecuteScript("console.log('Hi')");

It works to me, am I doing something wrong? @omer-za

[omer-za]

@nvborisenko Yes, please use the whole script i've sent above as the provided string.

chrome.webRequest.onHeadersReceived.addListener(
    function(details) {
        var responseHeaders = details.responseHeaders.filter(header => header.name !== 'X-Response-Body-Signature');
        return { responseHeaders };
    },
    {
        urls: ['https://something/vendors/*'],
    },
    ['blocking', 'responseHeaders', 'extraHeaders']
);

function makeRequest (method, url) {
    return new Promise(function (resolve, reject) {
        var xhr = new XMLHttpRequest();
        xhr.open(method, url);
        xhr.addEventListener('load', function () {
            if (xhr.status >= 200 && xhr.status < 300) {
                resolve(xhr.response);
            } else {
                reject({
                    status: xhr.status,
                    statusText: xhr.statusText
                });
            }
        });
        xhr.onerror = function () {
            reject({
                status: xhr.status,
                statusText: xhr.statusText
            });
        };
        xhr.send();
    });
}
makeRequest('GET', 'https://something');

[nvborisenko]

Unhandled exception. OpenQA.Selenium.JavaScriptException: javascript error: Cannot read properties of undefined (reading 'onHeadersReceived')

Please verify your script manually.

[omer-za]

I've set up script variable like this

var script = "\nchrome.webRequest.onHeadersReceived.addListener(\n    function(details) {\n        var responseHeaders = details.responseHeaders.map(\n            (header) => {\n                if (header.name === 'X-Context-Signature')\n                    header.value = 'bLrAdZ9t6/D//z/spDNOo2Dpjg8f/+/dLdYcXdEe8vdn05a/AqsWBfzeDvQ==';\n                return header;\n        });\n        return { responseHeaders };\n    },\n    {\n        urls: ['https://something/*'],\n    },\n    ['blocking', 'responseHeaders', 'extraHeaders']\n);\n \nfunction makeRequest (method, url) {\n    return new Promise(function (resolve, reject) {\n        var xhr = new XMLHttpRequest();\n        xhr.open(method, url);\n        xhr.addEventListener('load', function () {\n            if (xhr.status >= 200 && xhr.status < 300) {\n                resolve(xhr.response);\n            } else {\n                reject({\n                    status: xhr.status,\n                    statusText: xhr.statusText\n                });\n            }\n        });\n        xhr.onerror = function () {\n            reject({\n                status: xhr.status,\n                statusText: xhr.statusText\n            });\n        };\n        xhr.send();\n    });\n}\nmakeRequest('GET', 'https://something');\n;";

[nvborisenko]

And what is the issue? What exactly doesn't work?

[omer-za]

It just doesn't perform the request that it used to before upgrading the library, like that script is not being parsed correctly

[nvborisenko]

Just to understand whether this issue is really related to the library itself, I have to request you to collect logs https://www.selenium.dev/documentation/webdriver/troubleshooting/logging/:

• with previous version of the library where the script works
• with the latest version of the library where the script doesn't work

Then we will be able to compare the diff, thank you.

[omer-za]

Seems like there's some escaping issues introduced in 4.24.
The left one is 4.24 which doesn't includes '

[nvborisenko]

Chatted internally, it is not reproduced on my side.
