Directus

Overview

The "Utilities - Get a Random String" operation in this n8n node allows you to generate a random string of a specified length using the Directus API. This is useful in scenarios where you need unique identifiers, temporary passwords, tokens, or any other use case that requires a random alphanumeric string.

Practical examples:

• Generating a temporary password for a new user.
• Creating a unique token for session management.
• Producing random strings for testing or data anonymization.

Properties

Output

The output will be an object with a json field containing the result. The structure is as follows:

{
  "result": "<random_string>"
}

• result: The randomly generated string of the specified length.

If the API response is not an object (e.g., a plain string), it will still be wrapped in a result property for consistency.

Dependencies

• Directus API: Requires access to a Directus instance with the appropriate credentials configured in n8n (directusApi credential).
• API Key/Token: The node must be authenticated to the Directus API.

Troubleshooting

Common issues:

• Missing Credentials: If the required Directus API credentials are not set up, the node will fail to execute.
• Invalid Length: If the "Length" parameter is not provided or is less than 1, the API may return an error or a default-length string.
• API Connectivity: Network or authentication errors with the Directus API will cause execution failures.

Error messages and resolutions:

• "Cannot read property 'length' of undefined": Ensure that the "Additional Fields" collection is properly filled out and that "Length" is specified if needed.
• "401 Unauthorized" or similar: Check your Directus API credentials in n8n.
• "Network Error": Verify connectivity between n8n and your Directus instance.
