**Description**  
Instead share full screen, my business requires just share the canvas content to client in the webinar meeting  
Following Screen Sharing guild([https://marketplace.zoom.us/docs/sdk/video/web/essential/create-join-session](https://marketplace.zoom.us/docs/sdk/video/web/essential/create-join-session)) I use @zoomus/instantsdk to control screen sharing on html canvas tag. When I init client via code snippet:  
const client = ZoomInstant.createClient();  
// console.log(signature);  
client.init();  
client.join(  
“My Webinar”,  
signature,  
“xxx”,  
“xxxxxx”,  
).then(() =\> {  
console.log(‘Join meeting success’);  
}).catch((error) =\> {  
console.error(error);  
});  
I got error JOIN\_MEETING\_FAILED. The param in client.join method include: topic, username, password. I really wonder how to correctly set that values and how to join the meeting success. Please help me to fix this issue  
**Error**  
type: “JOIN\_MEETING\_FAILED”, reason: “This account does not exist or does not belong to you”, errorCode: 200

**Which Web Client SDK version?**  
zoom-instant-sdk-web: 1.0.3 2  
@zoomus/websdk: 1.8.6

Hi, @dungnp4,

Thank you for posting in the Developer Forum. First, please try testing with the latest version of the [**Web SDK (1.9.1)**](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk). You can test using our [Sample Web](https://github.com/zoom/sample-app-web) App to confirm if you see the same issue.There have been [multiple bug fixes](https://marketplace.zoom.us/docs/guides/stay-up-to-date/changelog) since your version of the SDK.

Best,  
Donte

Hi, @dungnp4,

Thank you for providing that update. It seems you’re authenticating with the wrong credentials. Are you able to confirm the correct credentials are being to used to access that account ? If that does the resolve the issue, would you be able to send your account details along with a linked to this tread to [developersupport@zoom.us](mailto:developersupport@zoom.us)? From there we can look at your account to troubleshoot.

Best,  
Donte
