Dear gurus,

 ![image](https://us1.discourse-cdn.com/flex002/uploads/idxcommunity/original/2X/c/c950a661912a16748e94fd0b0db380049597754c.png)  
i have no luck to fix it

- I added my domain in Firebase Auth \> Auth Domain
- Confirmed the project config (e.g. app id…) are put into config.js
- Restart my app many times
- 

The simulator still complain the same error
