Worker options for custom transport in pipeline not passed

[thyming]

Hi, thanks for your work on pino!
I am trying to create a pipelined transport and pass it a message port, like so:

import pino, { TransportPipelineOptions } from 'pino';
import { MessageChannel } from 'node:worker_threads';

const { port1, port2 } = new MessageChannel();
const logger = pino({
    transport: {
      pipeline: [
        {
          target: './transport.ts',
          worker: {
            workerData: {
              port: port1,
            },
            transferList: [port1],
          },
        },
        {
          target: 'pino-pretty',
          options: {
            sync: true,
            translateTime: 'HH:MM:ss Z',
            ignore: 'pid,hostname',
          },
        },
      ],
    } satisfies TransportPipelineOptions,
  });

When I run this code, it throws this error:

    TypeError: Object that needs transfer was found in message but not listed in transferList

      32 |               port: port1,
      33 |             },
    > 34 |             transferList: [port1],
         |                                ^
      35 |           },
      36 |         },

However, if I do not use a pipeline (omitting the pino-pretty transport) and create the transport like so

 pino(
    pino.transport({
      target: './transport.ts',
      worker: {
        workerData: {
          port: port1,
        },
        transferList: [port1],
      },
    }),
  );

everything works correctly.

Is there potentially an option I'm not passing or passing incorrectly to make this work with a pipeline?
Thanks!
