Functions Errors

All error responses use the standard envelope format:

{
  "meta": { "timestamp": "...", "correlationId": "..." },
  "errors": [{ "code": "FAAS-1004", "message": "Package with ID [...] was not found!" }]
}

The code field is a stable machine-readable identifier. The message field is a human-readable description that may include contextual details.
