Document → Answer Question
AI-generatedOverview
This node interacts with the Outline knowledge base service, specifically enabling users to perform various operations on documents and other resources within Outline. The "Answer Question" operation under the "Document" resource allows you to ask a question about a specific document and receive an AI-generated answer based on the document's content.
Common scenarios for this operation include:
- Automating customer support by querying product manuals or FAQs stored as documents.
- Extracting specific information from internal documentation without manual searching.
- Enhancing chatbots or virtual assistants with contextual answers derived from company knowledge bases.
For example, you could use this node to ask, "What is the return policy?" about a document containing your company's policies, and get a precise answer generated by AI.

Output
The output JSON contains the response from the Outline API's answer question endpoint. It typically includes the AI-generated answer to the provided question based on the specified document's content.
The exact structure depends on the Outline API but generally includes fields such as the answer text and possibly metadata about the response.
No binary data output is involved in this operation.
Dependencies
- Requires an API key credential for authenticating with the Outline knowledge base API.
- The node makes HTTP POST requests to Outline's endpoints to perform actions.
- Proper configuration of the Outline API credentials in n8n is necessary.
Troubleshooting
Common issues:
- Invalid or missing API credentials will cause authentication errors.
- Providing an incorrect or non-existent document ID will result in not found errors.
- Network connectivity problems can cause request failures.
Error messages:
- Authentication errors usually indicate invalid API keys; verify and update credentials.
- "Document not found" errors mean the specified document ID does not exist or is inaccessible.
- Rate limiting or quota exceeded errors require checking Outline API usage limits.
To resolve errors, ensure all required parameters are correctly set, credentials are valid, and the Outline service is reachable.
