# Debugging Deployed Custom Policies

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Errors that aren’t present in the PDK’s debugging and testing environments might be present when the
policy is [applied to an API instance](https://docs.mulesoft.com/pdk/1.9/policies-pdk-apply-policies) in a production environment.

To use debug logs in a production environment, see
[Troubleshooting Self-Managed Gateway with Debug Logs](https://docs.mulesoft.com/gateway/latest/troubleshoot-debug-logs).

For more information about monitoring Omni Gateway, see
