Improve types performance

**Problem**
When working with handlers, 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 handlers responsible for the reported error messages and read how errors are currently propagated. Determine which handler failures need more context, then verify that the resulting messages are more descriptive without obscuring the underlying errors.
