I am getting the same issue, if i import embedded package then it is working fine

Like " import ZoomMtgEmbedded from ‘@zoom/meetingsdk/embedded’; " is not causing any error but  
import { ZoomMtg } from ‘@zoom/meetingsdk’;  
this is getting me this \_ is not defined error

Does any one have solution ?

I’m having the same issue since rebuilding our existing Zoom integration. I can’t see where I’m missing what’s clearly a crucial bit of config at the moment but if I find it, I’ll let you know

Hey Mike, Thanks,  
Actually I have solved this \_ issue , it was because of the zoom lodash library was not loaded so i added `<script src="https://source.zoom.us/3.1.6/lib/vendor/lodash.min.js"></script>` in my index.html file in header tag in my ReactJS app and error is solved  
Hope this helps to you

Thanks for sharing @abhay.scaleteam! Unfortunately I haven’t figured out my issue yet but I’ve parked it for now. I have an Angular project within an Nx monorepo, although never had an issue like this with any other package.

Hi, I am having the same error.

I would prefer not to import lodash globally from the Zoom CDN. Is there another option?

If you’re facing this issue in a project that’s importing the SDK from npm, it’s because your project hasn’t defined loadash (a dependency for the Zoom SDK). You can import loadash by adding the `<script src="https://source.zoom.us/3.1.6/lib/vendor/lodash.min.js"></script>` to the `<head>` of your html file & solve the error.
