TargetClosedException in some webpages

[senken]

Hello,

I have encounter a problem while I try to get DOM from this page -> https://sycm.taobao.com/custom/login.htm
by using code below:

await Browser.WaitForInitialLoadAsync();
await using var context = await Browser.CreateDevToolsContextAsync();
var frameHandle = await context.QuerySelectorAsync("div[class='login-box'] iframe");

I will get a TargetClosedException then. So I have done a little research of the source code and find out that the FrameManager will receive "Runtime.executionContextCreated" message before any other messages. While the _asyncFrames is empty, try to get frame (FrameManager.cs: 242) would cause the PuppeteerException (AsyncDictionaryHelper.cs: 34) and close the connection.

I have try to fix it but no success, please kind help me, thanks a lot.

Is it an OOPIF? OOPIFs aren't currently supported.

You can try disabling site isolation trials as a potential workaround.

Thanks for reply!
I have followed the instruction to disabled the site isolation in the settings, but it still not working, Are there any chance that it will support OOPIF in the future?

@gunpal5 Are you trying to query an iframe?

Version 2.0.86 has a fix for a possibly related frame not found exception.
