error serializer question

[naseemkullah]

Is it possible to serialize an error err such that instead of the stack trace being (only) in err.stack it is (also) in a top level stack_trace property? If so, how?

This will come in handy for the google cloud pino plugin if it ever gets made: googleapis/nodejs-logging#875 (comment)

But I would use this config at our org in the meantime.

This is not currently possible without some significant manipulation of config file. I think you can use the log formatter to do so.

Ah, so instead of playing with the error serializer, you would suggest something like the following?

    log(object) {
      const stackTraceProp = object?.err?.stack
        ? {stack_trace: object.err.stack}
        : {};

      return {
        ...object,
        ...stackTraceProp,
      };

formatter, not serializer.

That's the only way to do what you'd like to do.

Alright thanks!
