Improve error messages in handlers

**Description**
Currently helpers lacks proper retry support.

**Proposed solution**
Add configurable retry with sensible defaults.

**Priority**: Low/Medium

Start by tracing the helpers and handlers described in the issue to understand the current error and retry paths. Confirm how configurable retries should interact with existing handler errors, then verify that sensible defaults and configurable retry behavior work consistently across the affected helpers.
