Unexpected token < - React app

I’m just setting up a component to test zoom into a react app and im getting an error. I guess is something related to jquery library or zoom source but i was not able to find the solution yet.
Im using jwtApp

Uncaught SyntaxError: Unexpected token ‘<’
VM101 5510_js_media.min.js:1 Uncaught SyntaxError: Unexpected token ‘<’

Which version?

@zoomus/websdk”: “^1.7.10”,

To Reproduce(If applicable)
Steps to reproduce the behavior:
just after component render

Additional context
This is the component code:

import React, { useEffect, useState } from 'react';
import styled from 'styled-components';
import axios from 'axios';

import { ZoomMtg } from '@zoomus/websdk';

import { Column, Row } from '../../components/Layout';

export const Container = styled(Column)`
  height: 100vh;
  margin: 20px;
  background-color: darkgrey;

export const Section = styled(Row)`
  padding-top: ${(props) => props.withPadding && '15px'};
  border-bottom: ${(props) => props.withBorder && '1px solid whitesmoke'};

const meetConfig = {
  apiKey: '',
  meetingNumber: '',
  leaveUrl: 'www.google.com.ar',
  userName: 'Test',
  role: 1 // 1 for host; 0 for attendee or webinar

export default () => {
  const [currentSignature, setCurrentSignature] = useState();

  useEffect(() => {
    const init = async () => {
      const {
        data: { signature }
      } = await axios.post('http://localhost:5001', {
        data: { meetingNumber: meetConfig.meetingNumber, role: 1 }
    ZoomMtg.setZoomJSLib('https://source.zoom.us/1.7.4/lib', '/av');


  }, []);

  const onClick = () => {
      debug: true,
      leaveUrl: 'www.google.com',
      success: () => {
          signature: currentSignature,
          apiKey: meetConfig.apiKey,
          meetingNumber: meetConfig.meetingNumber,
          userName: meetConfig.userName,
          userEmail: meetConfig.userEmail,
          passWord: meetConfig.passWord,
          success: (success) => {
          error: (error) => {

  return (
    <button type="button" onClick={onClick}>

and from the console, seems that is able to execute the loaders:

Thanks in advance.

Hey @avglive.developer,

I believe the issue is this line, notice how you are using a deprecated version of the Web SDK, 1.7.4.

Please try matching it with the version you stated you are using, 1.7.10. :slight_smile:


Thanks! that’s the problem. Sorry i’m pretty new on this, i didn’t knew that those have to match. Many thanks!
