Add rate limiting for compression

**Problem**
When working with handlers, 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 provides no files, tests, or handler entry point, and its title requests compression rate limiting while the body requests more descriptive error handling. First reconcile which scope is intended and locate the relevant handler paths; done should include the agreed behavior and coverage for the resulting errors or rate-limit handling.
