Zoom SDK integrated with react app

Hi every one …
I try to integrate zoom sdk with react app. I use @zoom/videosdk .
I generate the signature in nodejs backend.

The problem was when i want to join to meeting i get error with code 200,
The reason was ‘This account does not exist or does not belong to you’ .

Note : i use it as free, i didn’t pay any money for plan, is this necessary ?!

I’m sorry, my English is not native language …

Hi @alhmydymhmdjmal91 ,

Can you please clarify the exact version of the video sdk please and move this question to the appropriate video sdk forum?

Thank you,

@zoom/videosdk”: “^1.4.0”,
i am using zoom video sdk react sample code.
