Overview

The node provides an operation to process health card documents using AI. It accepts a health card file in various input formats and processes it to extract or analyze relevant information. This node is useful in healthcare automation workflows where digital health cards need to be interpreted, validated, or integrated into other systems.

Practical examples include:

• Extracting patient data from scanned health cards.
• Validating the authenticity of health card documents.
• Automating data entry by processing health card images or files received from external sources.

Properties

Output

The output is a JSON object containing the processed results of the health card. The exact structure depends on the AI processing but typically includes extracted data fields such as patient information, card validity, and other metadata derived from the health card document.

If the node outputs binary data (e.g., annotated images or PDFs), it will be included accordingly, representing processed versions of the health card.

Dependencies

• Requires access to an AI processing service capable of interpreting health card documents.
• Needs appropriate API credentials or authentication tokens configured in n8n to connect to the external AI service.
• Internet access may be required if providing the health card via URL.

Troubleshooting

• Common issues:

  • Incorrect input data type selected or mismatch between input data and selected type.
  • Invalid or inaccessible URL when using URL input type.
  • Malformed base64 string causing decoding errors.
  • Missing or incorrect binary property name when using binary data input.
  • API authentication failures due to missing or invalid credentials.

• Error messages and resolutions:

  • "Input binary property not found": Verify that the binary property name matches the actual binary field from the previous node.
  • "Failed to fetch health card from URL": Check the URL accessibility and correctness.
  • "Invalid base64 content": Ensure the base64 string is correctly encoded without extra characters.
  • "Authentication error": Confirm that the API key or token is properly set up in n8n credentials.
  • "Processing failed": Review the health card file format and ensure it is supported by the AI service.
