Add configuration options for retry

**Problem**
When working with routes, 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 does not identify any files, tests, or entry points. Start by locating route handling and the existing retry configuration, then determine where error messages are produced. Done means the retry behavior is configurable and route errors provide the requested additional detail, with tests covering the changes.
