# Zuplo Fatal Project Error (FATAL_PROJECT_ERROR)

There was a fatal error loading your Zuplo project. This error indicates a
critical failure that prevents the project from starting.

## Common causes

- **Corrupted deployment** - The deployment artifacts are invalid or incomplete.
- **Critical configuration errors** - The project configuration contains errors
  that prevent the runtime from initializing.
- **Infrastructure issues** - A temporary platform issue may prevent the project
  from loading.

## Recovery steps

1. Check the deployment logs in the Zuplo portal for specific error details.
2. Try redeploying the project. This resolves issues caused by transient
   infrastructure problems.
3. Review recent changes to the project configuration, routes, or code for
   anything that could cause a fatal error.
4. Roll back to a previous working deployment if available.

:::caution

This error affects all routes in the project. No requests can be processed until
the issue is resolved.
