# Error

- File ID: file:1awldsb:error-razor
- Path: NexusReader.Web/Components/Error.razor
- Role: ui-component
- Layer: frontend

## Purpose

Blazor UI component that displays a generic error message and, when available, expandable technical details from an Exception parameter.

## Key Details

Simple UI component: exposes Exception parameter, overrides OnInitialized (no implementation), renders static error UI and an expandable technical details block when Exception is provided.

## Symbols

- Error: Blazor UI component that displays a generic error message and, when available, expandable technical details from an Exception parameter.
- OnInitialized(): Component lifecycle hook called during initialization; currently contains a placeholder for logging the exception.
- Render (component markup): Renders a user-facing error message and conditionally shows expandable technical details when Exception is present.
- Error (component backing model): Generated component class backing the Error.razor file; exposes a Parameter to receive an Exception instance.
