/**
|
|
* Workflow Chat Component
|
|
*
|
|
* A drawer-based chat interface for testing and debugging workflow executions.
|
|
* Provides real-time streaming of workflow node execution status, input/output data,
|
|
* and error messages. Supports variable configuration and file attachments.
|
|
*
|
|
* Key Features:
|
|
* - Real-time workflow execution monitoring with SSE streaming
|
|
* - Node-level execution tracking (start, end, error states)
|
|
* - Variable configuration for workflow inputs
|
|
* - File upload support (images and documents)
|
|
* - Collapsible node execution details with input/output inspection
|
|
* - Error handling and display
|
|
*
|
|
* @component
