Overview

This node interacts with the OpenProject API to retrieve schema information about specific values properties. In particular, the "View Values Schema" operation under the "Values Property" resource allows users to fetch metadata or schema details for a given value identifier within OpenProject. This can be useful when you want to understand the structure, constraints, or expected format of certain fields before processing or displaying them in workflows.

Practical examples include:

  • Validating input data against the schema of a project property.
  • Dynamically generating forms or UI elements based on the schema of a value.
  • Automating data integration tasks where understanding the property schema is necessary.

Properties

Name Meaning
Id The identifier of the value whose schema you want to view. This corresponds to the property field of the Values resource and should be provided in lower camelcase format (e.g., startDate). It is required to specify which property's schema to retrieve.

Output

The node outputs JSON data representing the schema of the specified value property. This typically includes details such as data type, validation rules, possible options, and other metadata describing the structure and constraints of the value.

If the node supports binary data output, it would generally relate to any associated files or attachments linked to the value property, but this is not indicated in the provided code snippet.

Dependencies

  • Requires an active connection to the OpenProject API.
  • Needs an API authentication token or key configured in n8n credentials to authorize requests.
  • The base URL for the OpenProject instance must be set in the node's credential configuration.

Troubleshooting

  • Common issues:

    • Invalid or missing Id property: Ensure the id parameter is provided and correctly formatted in lower camelcase.
    • Authentication errors: Verify that the API key or token is valid and has sufficient permissions.
    • Network or connectivity problems: Confirm that the OpenProject server URL is reachable from the n8n environment.

  • Error messages:

    • Unauthorized or 401 errors indicate invalid credentials; reconfigure the API key.
    • 404 Not Found may mean the specified id does not exist; double-check the identifier.
    • 500 Internal Server Error suggests server-side issues; retry later or contact OpenProject support.
