The console error looks more like a credential issue. I would verify the Video SDK credentials you are using are correct. ---

@tuanthinhit You needed Video SDK Creds. For that, you first need to [create a Video SDK Dev account](https://zoom.us/buy/videosdk). Don’t worry you have free 10,000 mints with that account without any charges. Then [navigate](https://marketplace.zoom.us/develop/) click on Video SDK and get **SDK Creds**. Note: **Please use your working email for registration**. ---

During registration, you must select ‘Pay as You Go’ and enter your payment info. You will not be charged until you consumed 10,000 mints/ month. Then navigate > [@freelancer.nak](#): > > [navigate](https://marketplace.zoom.us/develop/) And get Video SDK Creds, Set those to your PureJS demo and build the demo. ---
