# Debugging Deployed Custom Policies

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

Errors that are not present in the PDK debugging playground or PDK’s integration might be present
when the policy is [applied to an API instance](https://docs.mulesoft.com/pdk/1.4/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 Flex Gateway, see
[Monitoring Omni Gateway](https://docs.mulesoft.com/gateway/latest/gateway-monitor).
