Handle edge cases in logging

**Problem**
When working with api, 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 the API logging and error-handling paths, then identify the edge cases that currently produce unhelpful messages. Done means the relevant errors provide more descriptive context and the affected behavior is covered by tests.
