Started getting 'errorCode: 3008, errorMessage: “Please init meeting first!”' after updating to 1.8.0

I started getting errorCode: 3008, errorMessage: “Please init meeting first!” even though I am initializing my meeting and the exact same code was working on @zoomus/websdk@1.7.10

Hi @evnts,

We’re happy to look into this for you. As a first step, can you provide your web SDK code snippet, or a Github repo link? This will help us to debug on our end.

Thanks, and looking forward to your sample!


This is our current component. This code works with @zoomus/websdk@1.7.10 and simply stops working when we change the lib to @zoomus/websdk@1.8.0

import queryString from 'query-string'
import { ZoomMtg } from '@zoomus/websdk'
import { get } from '../utils/promise' // This is simply a wrapper for a request using promise
import '@zoomus/websdk/dist/css/bootstrap.css'
import '@zoomus/websdk/dist/css/react-select.css'
import './css/zoom.css'

export default class Zoom extends Component {
  constructor () {
    this.state = {
      botaoHabilitado: true,
      naoCarregou: true,
      meeting: {}

  componentDidMount () {
    const opcoes = queryString.parse(
    if (opcoes.meetingNumber && opcoes.userName && opcoes.userEmail) {
      const meeting = {
        meetingNumber: opcoes.meetingNumber,
        userName: opcoes.userName,
        userEmail: opcoes.userEmail,
        passWord: opcoes.passWord || ''
      this.setState({ meeting }, () => { this.initialize() })

  join = () => {
    get(`/api/v1/autenticar/zoom/${this.state.meeting.meetingNumber}`).then(resposta => {
      if (!resposta || !resposta.success || ! {
        throw new Error('Não foi possível conectar ao Zoom')

        leaveUrl: window.location.href,
        isSupportChat: false,
        isSupportQA: false,
        showMeetingHeader: false,
        videoHeader: false,
        disableInvite: true,
        inviteUrlFormat: 'hide',
        error: erro => { erro && console.error(erro) },
        success: () => {
  , /* This response contains apiKey and signature */
            error: erro => { erro && console.error(erro) }

  initialize = () => {
    if (!ZoomMtg.checkSystemRequirements()) throw new Error('O Zoom não é suportado neste navegador')

    ZoomMtg.setZoomJSLib('/zoom/lib', '/av') // I made the lib available in the public folder

  render () {
    return <div id='zmmtg-root' />

Hey @evnts,

Thanks for getting back to me with your sample—after taking a quick look, I would recommend moving the following lines to immediately follow your import statements:

ZoomMtg.setZoomJSLib('/zoom/lib', '/av') // I made the lib available in the public folder

While this is not exactly the same, you’ll notice in our Angular sample app a similar approach:

It’s likely this will do the trick, but let us know if not!

Tried it. That specific error stopped. But now nothing happens after loading the /av files:

I tried using our local copies with ZoomMtg.setZoomJSLib('/zoom/lib', '/av') as well as, with ZoomMtg.setZoomJSLib('', '/av') to the same result. Nothing happens after loading the /av files…

There are console.log inside both init and join success callback functions and there are console.error inside both init and join error callback functions. This is all the output I get:

I also tried the same thing (moving those 3 lines to immediately follow the import statements) with the version that was working (1.7.10) and the behavior was the same. After loading the /av files nothing happens. So I don’t think that the problem is the position of those lines…

Hey @evnts,

Can you please provide your github repo link so we can reproduce and debug the issue locally? :slight_smile:


The code is available for download here:

You’ll have to replace the part where the app access /api/v1/autenticar/zoom/${this.state.meeting.meetingNumber} to get the apiKey and signature, because that part is not available in that code.

The app homepage is located at /zoom and the meeting info is retrieved via query parameters
Sample URL:
passWord is optional (the code assumes passWord='' when not informed

Hey @evnts,

Can you double check the download link? It downloaded an invalid file.

If you could put this on a GitHub repo it would be easier for me to get it up and running.


Hey @evnts,

I am having trouble starting your project. I am getting the following error/warning:

Here is the project structure, I have not changed anything in the public directory:


That’s because the map file for the JS is not available. (
Even when we use ZoomMtg.setZoomJSLib('', '/av') that happens.
Even when using 1.7.10 that happened.

That is not the problem. That’s a warning stating that the browser couldn’t find the map file for webim.min.js and that’s simply because you guys don’t provide a map file for your minified javascripts.
Like I said. That’s a warning. That does not stop the code from running.

The trouble you’re having is exactly the trouble I was having after I did what @will.zoom instructed here (Moving setZoomJSLib, preLoadWasm and prepareJssdk to immediately follow the import statements)

After the page loads the wasm files, nothing else happens.

Hey @evnts,

Gotcha, I will take another look at this and report back when I find the issue.


Hey @evnts,

I was able to get it working! :slight_smile:

I just moved the Zoom pre and set lib functions to the top of the file like so:

import React, { Component } from 'react'
import queryString from 'query-string'
import { ZoomMtg } from '@zoomus/websdk'
import { get } from '../utils/promise'
import '@zoomus/websdk/dist/css/bootstrap.css'
import '@zoomus/websdk/dist/css/react-select.css'
import './css/zoom.css'

ZoomMtg.setZoomJSLib('/zoom/lib', '/av')

Please try that and let me know if it works! :slight_smile:

@tommy I just noticed that the code I posted on github is using @zoomus/websdk@1.7.10 and I’m having trouble with version @zoomus/websdk@1.8.0

I’m sorry about that. I updated the repo to use @zoomus/websdk@1.8.0

What I reported earlier is still happening:

  • When setZoomJSLib, preLoadWasm and prepareJssdk are inside the initialize function I get the “Please init meeting first!” error.
  • When I move them to the top I get a few “pre load wasm success” on the console, but then nothing else happens

Hey @evnts,

Are you able to put console logs so you can see exactly where the code stops? Are their any errors in the browser console?


No errors. Only the logs “pre load wasm success” and nothing else.

Even with console.log inside init.success and join.success and console.error inside init.error and join.error

Did you tried running the code with SDK version 1.8.0? Did it work?

I am running into same issue in React.

It was working fine with prev version but as soon as i upadated to 1.8.0, I faced the issue : please init meeting first.

Then, as @will.zoom suggested, i moved
ZoomMtg.preLoadWasm(); ZoomMtg.prepareJssdk()
these to top

Now, ZoomMtg.init() itself is not working (there is no success or error message)

Hey @evnts,

Yes, I got it to work. Are you sure you are calling your start/join meeting function to execute the Web SDK init and join code?


Hey @saurssaurav33,

Can you please provide steps to reproduce the issue and your Web SDK code so we can take a look? :slight_smile:

Hello @tommy,
I haved created Repo to re-create the issue. Here is the link,

And i have also created another branch v.1.7.8 (everything is same, only the version is different) on the repo where the zoomsdk runs perfectly.

Thank you for your time.
