Handle edge cases in logging

**Problem**
When working with store, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

Start by locating the store and its logging or error-handling entry points, then reproduce the reported edge cases to identify where messages lose useful context. Done means the relevant failures produce more descriptive error messages and the behavior is covered by appropriate tests.
