Hello, @chunsiong.zoom I’ve been encountering issues while integrating the Zoom Video SDK in my React Native project. I have followed the provided code from the official GitHub repository and tried multiple SDK versions without success. Specifically, I’m facing the following errors: - **TypeError: null is not an object (evaluating ‘RNZoomVideoSdkChatHelper.isChatDisabled’)** This error indicates that the `RNZoomVideoSdkChatHelper` object is `null`, which seems to suggest that the Zoom SDK is not being initialized properly. - **Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)** This occurs repeatedly and points to potential issues with the application’s entry file or improper bundling. My environment details are as follows: - **React Native version:** 0.64.4 - **Development setup:** React Native CLI I have tried several troubleshooting steps, including: - Verifying the Zoom SDK initialization and imports. - Checking the application’s entry file and ensuring proper registration with `AppRegistry`. - Clearing the cache and rebuilding the project. - Testing different versions of the Zoom SDK. However, none of these approaches have resolved the issue. Is there any known workaround or specific setup required for using the Zoom SDK with React Native version 0.64.4? Thank you. ---

I get the same error: `TypeError: Cannot read property 'isChatDisabled' of null, js engine: hermes` When using the [videosdk-reactnative-quickstart](https://github.com/zoom/videosdk-reactnative-quickstart), any idea why?
