I can't open the collapsed live chat

15:14:22.763 TypeError: this.document is null ChatIframe.js:31:5

Showing this everytime I click it

There is no "ChatIframe.js" in YouTube.

I think it could be due to conflicts with your other browser extensions or userscripts.

Please disable them all first and try again. Then test one by one to see which caused the conflict.

Are you using an extension called "YouTube Livestreams Theater Mode" ?

I can reproduce your issue using YouTube Livestreams Theater Mode

I have tried a bit, and I don't think it is working well in the current latest YouTube stable layout.

Anyway, I think there are some conflicts with it. You might have to disable either one of them to use YouTube.

Now it works, I don't know why but now I can't close the chat and it will always load

"Now it works" I mean without disabling anything, I just restart the browser

There is a bug in its coding.

  initDocument() {
    this.document = this.element.contentDocument;
    this.html = this.document.querySelector('html');
    if(this.isReady()) {
      this.initContent();
    }
    else {
      setTimeout(this.initDocument.bind(this), 100);
    }
  }

Change

this.html = this.document.querySelector('html');

to

this.html = this.document?.querySelector('html');

I cannot find a proper way to report the issue to the author.

You might ask him to join the discussion here or GitHub.

The same after disabling "YouTube Livestreams Theater Mode"

What is the error message now?

15:14:22.763 TypeError: this.document is null ChatIframe.js:31:5 would not appear if you have disabled "YouTube Livestreams Theater Mode"

Oh. You are right. Let me find out the root cause and get back to you.

It seems to be Firefox specific.

I have found the cause which is the bug in this script.

Fixed in 0.37.7.

You can use "YouTube Livestreams Theater Mode" as well. (it seems no conflict)

The fix works, I use a script that made the chat auto collapse and it stops working. Thank you.

The live chat will get stuck after a while

Yes... I feel the same... I am not sure whether it is caused by this script, or YouTube Super Fast Chat, or conflict between both.

I cannot locate the root cause at this moment...

The live chat will get stuck after a while

I just lighted upon that, I should have found the issue that making the chat message get sucked, and fixed some days ago.

Make sure you have updated "YouTube Super Fast Chat" to v0.102.9 (or later) and try again.

Tell me if it does not work for you.

it got fix somehow
