Fix DataConnectError

✅ Solution

The "DataConnectError" in firebase-sdk often arises from TypeScript compilation issues when `skipLibCheck` is disabled, particularly due to incompatible or outdated type definitions within your project or its dependencies. To resolve this, try updating all firebase-related packages to their latest versions using `npm update` or `yarn upgrade`, and ensure your `tsconfig.json` includes a compatible TypeScript version. Consider enabling `skipLibCheck` as a temporary diagnostic step or if a full type check isn't strictly necessary.
