Add rate limiting for timeout

**Problem**
When working with helpers, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names no files, tests, or entry points. First clarify whether the goal is timeout rate limiting or more descriptive helper errors, then locate the relevant helper and timeout/error-handling paths. Define the expected behavior and messages before implementing and testing the change.
