Add rate limiting for monitoring

**Problem**
When working with store, 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 reconcile the title's monitoring rate-limiting request with the body’s request for more descriptive store errors, then locate the relevant monitoring and store paths. Done should be defined as either rate limiting monitoring activity or adding the requested detailed error messages, with tests covering the chosen scope.
