records must be a non-empty array of {id?, vector, text?}

Error message

records must be a non-empty array of {id?, vector, text?}

What it means

Thrown by the agenticow_ingest MCP tool handler when the `records` argument is not a non-empty array. Ingest is the write half that populates a branch or base with vectors, so at least one record shaped {id?, vector, text?} must be present. The guard runs before any lineage file is opened.

Solutions

  1. Pass records as an array with at least one element: [{ vector: [0.1, ...] }].
  2. If your batch is empty, skip the ingest call entirely rather than invoking with [].
  3. Guard the call site with Array.isArray(records) && records.length > 0 before invoking.
  4. Confirm each element is an object with a vector field (the next check, error 243, enforces that).

Example fix

// before
agenticow_ingest({ path, records: record })
// after
agenticow_ingest({ path, records: [record] })
Defensive patterns

Strategy: validation

Validate before calling

function validateIngestRecords(records) {
  if (!Array.isArray(records) || records.length === 0) {
    throw new Error('records must be a non-empty array');
  }
  return records;
}

Type guard

function isIngestRecordArray(v: unknown): v is Array<{ vector: number[] }> {
  return Array.isArray(v) && v.length > 0 && v.every((r) => r && typeof r === 'object' && Array.isArray((r as any).vector));
}

Prevention

When it happens

Trigger: Calling agenticow_ingest with records omitted, null, a non-array value (object/string), or an empty array []. The JSON schema marks records as required, but runtime callers bypassing the schema still hit this.

Common situations: Passing records as a single object instead of an array; an upstream filter producing zero records; deserialisation yielding undefined when the field was absent.
