OpenProjectInstall

Overview

This node interacts with the OpenProject API to retrieve a specific custom field item by its unique identifier. It is useful when you need to fetch detailed information about a particular custom field item within an OpenProject instance, such as for reporting, automation, or integration purposes.

A practical example would be automating the retrieval of custom field details to update other systems or trigger workflows based on the custom field's value.

Properties

Output

The node outputs JSON data representing the retrieved custom field item from OpenProject. The structure typically includes all properties of the custom field item as returned by the OpenProject API, such as its id, name, and any associated metadata.

If the node supports binary data output (not indicated here), it would represent file attachments or similar content related to the custom field item, but this is not evident from the provided code.

Dependencies

• Requires an API key credential for authenticating with the OpenProject API.
• The base URL of the OpenProject instance must be configured in the node credentials.
• Depends on the @devlikeapro/n8n-openapi-node package for building request properties and handling API interactions.
• Uses an OpenAPI specification (openapi.json) bundled with the node to define available operations and parameters.

Troubleshooting

• Common issues:

  • Invalid or missing API credentials will cause authentication failures.
  • Providing an incorrect or non-existent custom field item ID will result in errors or empty responses.
  • Network connectivity problems to the OpenProject server can cause timeouts or connection errors.

• Error messages:

  • Authentication errors typically indicate invalid API keys or insufficient permissions; verify credentials and access rights.
  • "Not Found" errors suggest the specified custom field item ID does not exist; double-check the ID value.
  • Timeout or network errors require checking the OpenProject server availability and network configuration.
