Optimize auth for large datasets

**Problem**
When working with components, 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 component authentication and error-handling entry points, then review how current errors are constructed and surfaced. Define the cases that need more descriptive messages and verify that the resulting messages improve debugging without changing unrelated behavior.
