I am facing an error in my production build. but in development build its working with different error. I know most of developers are facing this same problem. I have implement a custom-webpack.config.js which i was found in this forum. I was Simply followed full instraction from [https://marketplace.zoom.us/docs/sdk/native-sdks/web/getting-started/integrate](https://marketplace.zoom.us/docs/sdk/native-sdks/web/getting-started/integrate). and it works in my localhost:4200 but when I have build with production configuration then I found an error like : “Uncaught Error: Uncaught (in promise): TypeError: Super expression must either be null or a function, not undefined”. Then I was searched for solution in web by googling finally i found a solution in this devforum .zoom.us . ![Screenshot_12](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/f/f9a2388288a9313c8185698b6720907a7d40940e.png) What will be the solution for final purchase from zoom we have a launch date in december.

Hi, I have the same issue. It works in my local app, but doesn’t work on dev server. Getting the same error as @mahabub. Do you have some new info? I use @zoomus/websdk": “1.7.5” ---
