# ROUTER_TOO_MANY_HAS_SELECTIONS

The `ROUTER_TOO_MANY_HAS_SELECTIONS` error occurs when the router encounters too many selections while processing the request. This could happen due to misconfiguration or a complex routing setup that exceeds the router's capabilities.

## Troubleshoot

To troubleshoot this error, follow these steps:

1. **Review routing configuration:** Check the [routing configuration](/docs/redirects#configuration-redirects) to ensure it's correctly set up and doesn't contain excessive selections
2. **Simplify routing setup:** If possible, simplify the routing setup to reduce the number of selections the router has to process
3. **Check for recursive or looping logic:** Ensure there isn't any recursive or looping logic in the routing configuration that could lead to excessive selections
4. **Review application logs:** Inspect the [application logs](/docs/deployments/logs) for any warnings or errors related to routing or selections
