customPrettifiers DataCloneError #359

Closed mgcrea closed 2 years ago

mgcrea commented 2 years ago

Tried to play with customPrettifiers to see what could be done and I'm encountering a worker related error:

const prettifyTime = (value) => {
  return new Date(value).toISOString();
};
const prettyOptions: PrettyOptions = {
  ignore: 'pid,hostname',
  customPrettifiers: {
    time: prettifyTime,
  },
};
const logger: : FastifyServerOptions['logger'] = {
  transport: {
    target: 'pino-pretty',
    options: prettyOptions,
  },
}

Leads to:

DataCloneError: (value) => {
    return new Date(value).toISOString();
} could not be cloned.

Transports cannot serialize a function to pass into the worker.
