Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Typo The word "Recieved" is misspelled in the log message. Should be "Received" LogTrace("Recieved Event {0}: {1}", method, loggableEventData.ToString()); Error Handling The code assumes postData and request properties exist and can be accessed without null checks, which could lead to NullReferenceException var loggableRequest = loggableEventData["request"]!; loggableRequest["postData"] = "*RAW POST DATA REMOVED FROM LOGS*"; loggableRequest["postDataEntries"] = new JsonArray();

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add defensive programming by validating JSON data before access to prevent runtime exceptions Add null check for eventData before accessing it to prevent potential NullReferenceException dotnet/src/webdriver/DevTools/DevToolsSession.cs [603] -if (eventData.AsObject().TryGetPropertyValue("request", out var requestNode) +if (eventData != null && eventData.AsObject().TryGetPropertyValue("request", out var requestNode) Apply this suggestion Suggestion importance[1-10]: 8 Why: This is an important defensive programming suggestion that could prevent runtime crashes. The null check is crucial when dealing with JSON data that might be malformed or incomplete.	8
General	Correct spelling error in log message to maintain code quality and professionalism Fix the typo in the log message where "Received" is misspelled as "Recieved" dotnet/src/webdriver/DevTools/DevToolsSession.cs [610] -LogTrace("Recieved Event {0}: {1}", method, loggableEventData.ToString()); +LogTrace("Received Event {0}: {1}", method, loggableEventData.ToString()); Apply this suggestion Suggestion importance[1-10]: 3 Why: While this is a valid correction of a spelling mistake ("Recieved" to "Received"), it's a minor issue that only affects log messages and doesn't impact functionality.	3

Repro test:

[Test]
public void AAA()
{
    driver.Manage().Network.StartMonitoring().GetAwaiter().GetResult(); // this enables serialization
    driver.Navigate().GoToUrl("https://tus.io/demo");

    Thread.Sleep(10_000);
    driver.FindElement(By.Id("P0-0")).SendKeys("C:\\Users\\Nick\\Downloads\\Firefox Installer.exe");

    Thread.Sleep(60_000);
}

Passes both on Firefox and Chrome.

That's my bad for forgetting the file header. Fixed.
