Knowledge bases

Create chunk

Append a chunk and embed it before returning. It inherits the document's tags and next `chunkIndex`. Search includes it when the chunk and document are enabled and the document has completed processing. Connector-synced chunks are read-only and return `403` with `error.details.code: "CONNECTOR_MANAGED_RESOURCE_READ_ONLY"`; change the source and re-sync, or exclude the document. Workspace API keys return `403`; use a personal API key or scoped OAuth token. OAuth scope: `api:write`.
