Protocol error(Runtime.callFunctionOn): Target closed.

Description

It happens only if you’re using Proxies, after logging in, when the page redirects you. You get the error, I can’t share the website or the code 😦 When the error occurs, the page is still open, it’s not closed.

Full Error

Protocol error(Runtime.callFunctionOn): Target closed. (NetworkManager failed to process Fetch.requestPaused. Value cannot be null. Parameter name: key. at System.Collections.Concurrent.ConcurrentDictionary2.GetOrAdd(TKey key, Func2 valueFactory) at PuppeteerSharp.Helpers.MultiMap2.Add(TKey key, TValue value) at PuppeteerSharp.Helpers.AsyncDictionaryHelper2.<GetItemAsync>d__4.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at PuppeteerSharp.NetworkManager.<OnRequestAsync>d__46.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at PuppeteerSharp.NetworkManager.<OnRequestPausedAsync>d__45.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at PuppeteerSharp.NetworkManager.<Client_MessageReceived>d__40.MoveNext())

Redirects just fine without the error occurring

Actual behavior:

That error occurs

Fixed on #1521 thank you @kerohero! I hope this is the first PR of many to come!

@kblok @Solaflex So I downloaded Puppeteer Sharp code and added it to my project to debug it The problem is in the NetworkManager file, the OnRequestAsync method, specifically in this line var frame = await FrameManager.TryGetFrameAsync(e.FrameId).ConfigureAwait(false); e.FrameId being null causes the exception, I gone to check Puppeteer itself and found this const frame = event.frameId ? this._frameManager.frame(event.frameId) : null; As you can see the frame itself can be null so I adjusted the code to be var frame = !string.IsNullOrEmpty(e.FrameId) ? await FrameManager.TryGetFrameAsync(e.FrameId).ConfigureAwait(false) : null; Works like a charm for me.
