```bash
[Error: You cannot use different slug names for the same dynamic path (‘orderId’ !== ‘orderNumber’).]
```

I’ve been building an app for almost 8 months now, and I’ve invested a lot of time and money. Recently, there was an update to v0 that has been causing my app to crash. My app will not load, and if I continue to push for fixes. It just breaks down my app and tears away Everything I have built. I have been asking VO for real help, and they are not helping me.}
