BookStack

Overview

This node integrates with the BookStack API to manage various resources such as books, pages, chapters, shelves, users, roles, attachments, and tags. Specifically, for the Attachment - Get operation, it retrieves a single attachment resource by its ID from the BookStack system.

Common scenarios where this node is beneficial include:

• Fetching metadata or details of a specific attachment stored in BookStack.
• Automating workflows that require accessing attachment information for documentation or processing.
• Integrating BookStack attachments into other systems or reports.

For example, you might use this node to get an attachment's details by providing its ID, then use that data downstream to display or process the attachment information.

Properties

Output

The node outputs JSON data representing the requested attachment resource. The structure corresponds directly to the BookStack API response for an attachment, typically including fields such as attachment metadata (e.g., name, URL, size, creation date).

If the attachment includes binary data (such as the actual file content), this node does not explicitly handle binary output in the provided code; it focuses on retrieving the attachment's metadata via the API.

Dependencies

• Requires connection to a BookStack instance via its API.
• Needs an API token credential consisting of a base URL and authentication tokens.
• The node uses HTTP requests with authorization headers set using these credentials.
• Pagination and other request defaults are configured but not relevant for single "Get" operations.

Troubleshooting

• Missing or invalid ID: The node requires a valid attachment ID. If omitted or incorrect, the API will return an error indicating the resource was not found.
• Authentication errors: Ensure the API token credentials are correctly configured with valid tokens and base URL.
• Network issues: Connectivity problems to the BookStack server will cause request failures.
• API changes: If the BookStack API changes, the node may fail to retrieve attachments properly until updated.

Common error messages might include:

• 404 Not Found if the attachment ID does not exist.
• 401 Unauthorized if the API token is invalid or missing.
• 500 Internal Server Error if the BookStack server encounters an issue.

Resolving these usually involves verifying the ID, checking credentials, and ensuring the BookStack service is operational.
