List Dataset Nodes - Graphor Docs

Retrieve all dataset nodes from a specific flow in your Graphor project. Dataset nodes represent the document sources configured within a flow and are essential for managing the data inputs to your RAG pipelines.

Overview

The List Dataset Nodes endpoint allows you to retrieve information about dataset nodes within a flow. Dataset nodes are components that connect document sources to your flow pipeline, containing configuration details about which files are included and how they’re processed.

Method: GET
URL: https://{flow_name}.flows.graphorlm.com/datasets
Authentication: Required (API Token)

Authentication

All requests must include a valid API token in the Authorization header:

Authorization: Bearer YOUR_API_TOKEN

Learn how to generate API tokens in the API Tokens guide.

Request Format

Headers

Header	Value	Required
`Authorization`	`Bearer YOUR_API_TOKEN`	Yes

Parameters

No query parameters are required for this endpoint.

Example Request

GET https://my-rag-pipeline.flows.graphorlm.com/datasets
Authorization: Bearer YOUR_API_TOKEN

Best Practices

Monitoring and Management

Regular Health Checks: Monitor dataset nodes to ensure they’re configured properly
Configuration Validation: Verify that all referenced files exist in your sources
Update Tracking: Keep track of which nodes need updates after configuration changes
Documentation: Maintain clear naming conventions for dataset nodes

Performance Optimization

Efficient Polling: Don’t poll this endpoint too frequently; cache results when possible
Batch Operations: Group multiple dataset node operations together
Resource Monitoring: Monitor the impact of dataset size on flow performance

Error Handling

Network Resilience: Implement retry logic for network failures
Graceful Degradation: Handle cases where flows have no dataset nodes
Detailed Logging: Log dataset node configurations for debugging

Troubleshooting

Flow Not Found Error

Solution: Verify that:

The flow name in the URL is correct and matches exactly
The flow exists in your project
Your API token has access to the correct project
The flow has been created and saved properly

Empty Dataset Nodes Array

Solution: If no dataset nodes are returned:

Verify the flow contains dataset components
Check that dataset nodes have been added to the flow
Ensure the flow has been saved after adding dataset nodes
Confirm you’re checking the correct flow

Missing Files in Configuration

Solution: If dataset nodes reference non-existent files:

Use the List Sources endpoint to verify file availability
Upload missing files using the Upload Source endpoint
Update dataset node configuration to remove references to deleted files

Outdated Node Status

Solution: If nodes show "updated": false:

The node configuration has changed since last processing
Use the Update Dataset endpoint to apply changes
Re-run the flow after updating configurations
This is normal after adding/removing files from the dataset

Connection Issues

Solution: For connectivity problems:

Check your internet connection
Verify the flow URL is accessible
Ensure your firewall allows HTTPS traffic to *.flows.graphorlm.com
Try accessing the endpoint from a different network
