Support retry configuration

**Problem**
When working with controllers, 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. Start by locating controller error handling and any existing retry-related configuration, then determine the intended configuration surface and affected error messages. Done means the retry behavior and detailed errors are specified and covered by appropriate tests.
