Improve error messages in hooks

**Feature request**
It would be great to have logging for middleware.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_logging` with default `false`.

Start by locating the hooks or middleware entry point and the existing configuration handling. Review current tests for hook behavior and configuration, then add coverage for the new option; done means logging is disabled by default and can be enabled with `enable_logging` for middleware.
