I am developing an application with zoom integration. I can connect to the conference, but there are many errors in the console. And i use angularjs

**Error**  
zoomus-websdk.umd.min.js:2 GET [https://rwcprod.zoom.us/wc/ping/3203682505?ts=1617685160769&auth=TLcrMTBjJLY4F8QR0B1FYr1HzI9x5bEXftkjVEZBWeY&rwcToken=kUutq\_Ou64zrxyyocZ4bNzCJKTs8Pl2fOV8JNJgGWVg&dmz=1](https://rwcprod.zoom.us/wc/ping/3203682505?ts=1617685160769&auth=TLcrMTBjJLY4F8QR0B1FYr1HzI9x5bEXftkjVEZBWeY&rwcToken=kUutq_Ou64zrxyyocZ4bNzCJKTs8Pl2fOV8JNJgGWVg&dmz=1) net::ERR\_CERT\_COMMON\_NAME\_INVALID  
Warning: Failed prop type: The prop `id` is required to make `n` accessible for users of assistive technologies such as screen readers.  
Warning: React does not recognize the `pullLeft` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `pullleft` instead. If you accidentally passed it from a parent component, remove it from the DOM element.  
Zoom/websdk version 1.9.1

Hey @pauchok,

Thank you for reaching out to the Zoom Developer Forum. I recommend reviewing our [Sample Angular App](https://github.com/zoom/websdk-sample-angular) in order to identify any potential issues. You can use that codebase as a reference when building out your application. You can also test with the sample app to see if an issue is related to your implementation or the functionality of the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk).

I hope that helps! Let me know if you have any questions.

Thanks,  
Max
