# Execute and Verify Pipeline

> Run your data conversion workflow and monitor execution status

## Running Your Workflow

### Starting the Workflow

1. Once your workflow is configured with input, conversion, and output nodes, click the **Run Workflow** button in the top-right corner
2. The system will begin processing your data according to the workflow configuration

## Monitoring Execution

### Run History

After starting the workflow:

1. Check the **Run History** section in the workflow overview panel
2. You'll see entries showing:
   * Execution start time and date
   * Workflow status (started, completed, failed)
   * Node and edge count (e.g., "3n/2e" for 3 nodes and 2 edges)

### Real-time Updates

* The UI updates progressively every 10 seconds during execution
* Monitor the status in the Run History section
* Watch for any error messages or warnings

## Handling Errors and Warnings

### Error Detection

If there are issues with your workflow configuration:

1. The system will display a warning panel showing the number of issues found
2. Each issue will be clearly explained with specific details
3. Common issues include:
   * Invalid file extensions for specified formats
   * Missing required configuration fields
   * Invalid file paths

### Fixing Issues

1. Review the error messages carefully
2. Check that file extensions match the expected format (e.g., `.geojson` for GeoJSON files)
3. Verify that all required fields are properly configured
4. Make necessary corrections and re-run the workflow

## Workflow Overview

The workflow overview panel provides a summary of your pipeline:

* **Inputs** - Lists all input nodes and their configurations
* **Conversions** - Shows conversion nodes and their transformations
* **Outputs** - Displays output nodes and their destinations

This overview helps you verify that your workflow is properly configured before execution.
