Improve error messages in helpers

**Feature request**
It would be great to have timeout for helpers.

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

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

Start by locating the helper implementation and the configuration-loading entry point; the issue names no files or tests. Trace how helper execution currently works, then define and verify the `enable_timeout` option with a default of `false` and confirm the requested timeout behavior for production use.
