  • instance: the Pino instance associated with the function
  • arguments: the arguments passed to the function
• tracing:pino_asJson:end: emitted at the end of the final serialization process. The emitted event payload has the following fields:
  • instance: the Pino instance associated with the function
  • arguments: the arguments passed to the function
  • result: the finalized, newline delimited, log line as a string
