Overview
This node allows you to view details of a placeholder user within the "Principals" resource in OpenProject. It is useful when you need to retrieve information about a specific placeholder user by their unique identifier. For example, you might use this node to fetch and display metadata about a placeholder user for auditing or reporting purposes.
Properties
| Name | Meaning |
|---|---|
| Id | The unique identifier of the placeholder user you want to view. This is a required string input. |
Output
The node outputs JSON data containing the details of the specified placeholder user. The structure typically includes user attributes such as name, ID, and other relevant metadata provided by the OpenProject API for that placeholder user.
No binary data output is expected from this operation.
Dependencies
- Requires an API key credential for authenticating with the OpenProject API.
- The node depends on the OpenProject REST API endpoint configured via credentials, including the base URL.
- The node uses standard HTTP headers for JSON content negotiation.
Troubleshooting
Common issues:
- Invalid or missing placeholder user ID will result in errors or empty responses.
- Incorrect or expired API credentials can cause authentication failures.
- Network connectivity problems may prevent successful API calls.
Error messages:
- 404 Not Found: The specified placeholder user ID does not exist. Verify the ID is correct.
- 401 Unauthorized: Authentication failed due to invalid API credentials. Check and update your API key.
- 400 Bad Request: The input parameters are malformed or missing. Ensure the "Id" property is provided and correctly formatted.
