Zoom chat window appear in unexpected location

The zoom chat window does nest in the located div but it comes in a different div and override all css properties.

Which Web Meeting SDK version?

Meeting SDK Code Snippets
The code snippets that are causing the error / issue so we can reproduce.

    const zmClient = ZoomMtgEmbedded.createClient();
    let meetingSDKChatElement = document.getElementById('meetingSDKChatElement')
    const vw = Math.max(document.documentElement.clientWidth || 0, window.innerWidth || 0)
    const vh = Math.max(document.documentElement.clientHeight || 0, window.innerHeight || 0)
    await zmClient.init({
        zoomAppRoot: document.getElementById(conf.zoomAppRoot),
        assetPath: conf.assetPath,
        language: 'ja-JP',
        customize: {
            video: {
                viewSizes: {
                        width: vw * 0.9,
                        height: vh * 0.4
            chat: {

This is the div that I specified

But the chat window appears here instead

Device (please complete the following information):

  • Device: [Macbook Pro]
  • OS: [macOS 12]
  • Browser: [Chrome]
  • Browser Version [Version 103.0.5060.134 (Official Build) (x86_64)]

Additional context
I literally copy and paste the code from

The widgets are out of place as well. Is caused by the new version??

check the result of “let meetingSDKChatElement = …”, does it finds the correct DOM node?


Yes it does. I tested in the console.

don’t check this problem in the brower debug console - check it directly in your javascript

for objects maybe even: console.log(JSON.stringify(obj));

if your javascript is executed too early, it may be that the DOM tree is not yet rendered, then javascript will not find DOM node

if all timing errors are excluded, you can of course test very well in the brower debug console


Yes I am fully aware of what you are saying. And it does feel like a logical reason of why this would not work. I changed the console.log and it can output the correct div. So this was not the problem.

then it seems to be a zoom api error. The big Javascript patch solution ’ mutationobserver’ → move the complete sub DOM tree to the correct position is probably not an adequate solution for this problem.
