AvantGuard - HuduInstall

Overview

The AvantGuard - Hudu node's "Update List" operation allows users to update an existing List resource in the Hudu system. This is useful for scenarios where you need to modify the details or items of a list, such as updating task lists, inventories, or any structured data collections managed within Hudu.

Practical examples:

• Updating a checklist with new items for a project.
• Modifying inventory lists to reflect current stock.
• Adjusting shared resources or documentation lists in an IT environment.

Properties

Name	Type	Meaning
Id	Number	ID of the List to update. Specifies which list will be modified.
Additional Body Fields	Collection	Optional fields to include in the request body. Allows adding extra data to the update.
└─ List	JSON	A JSON object representing additional attributes for the list, such as list_items_attributes.

Output

The node outputs a json field containing the response from the Hudu API after updating the specified list. The structure of this output will typically mirror the updated list object as returned by the Hudu API, including all its properties and any changes made.

Note: If the API returns binary data (unlikely for this operation), it would be included in the output as a binary property.

Dependencies

• External Service: Requires access to a Hudu instance with API enabled.
• API Key/Credentials: Needs valid credentials (avantguardHuduApi) configured in n8n, including the base URL and authentication token.
• n8n Configuration: Ensure the credentials are set up in n8n under the name avantguardHuduApi.

Troubleshooting

Common Issues:

• Invalid List ID: If the provided Id does not correspond to an existing list, the API may return a "Not Found" error.
• Authentication Errors: Missing or incorrect API credentials will result in authentication failures.
• Malformed JSON: If the "List" field in Additional Body Fields contains invalid JSON, the request will fail.

Error Messages & Resolutions:

• "404 Not Found": Check that the Id matches an existing list in Hudu.
• "401 Unauthorized": Verify your API credentials in n8n.
• "400 Bad Request": Ensure the JSON in "List" is correctly formatted and includes valid attributes.
