function properties of a job data are not available in the worker callback

[Sin13]

it looks like we cant have functions as properties in a job data. they are in fact there when i create them, as you can see in the log below (its called the fillerFunction):

but when i log the job again in the worker callback, the fillerFunction property is nowhere to be seen:

i create the jobs like this:

      const flow = await flowProducer.add({
        name: 'certificate setup',
        queueName,
        children: [
          {
            name: 'activate Certificate',
            data: {
                type: 'activate',
                description: 'certificate activation',
                url: '',
                method: 'post',
               collection: 'ssl_tls_certificate_v2',
               filter: {
                // some code
               },
               details: {
                // some code
               },
               fillerFunction: function () {
                 console.log('testing');
               },
               cool: 'ok its cool',
             },
            queueName,
          },
        ],
      });

      console.log('🚀 ~ file: setup.ts ~ line 46 ~ setup ~ flow', flow.children![0]);

and the worker code is like this:

const worker = new Worker(
    queueName,
    async (job) => {
      console.log('🚀 ~ file: generateWorker.ts ~ line 33 ~ job.data', job.data);
      if (job.data.fillerFunction) job.data.fillerFunction();
      const result = await handleJob(job.data);
      return result;
    },
    {
      connection: config.redisConnection,
    },
  );

my bad! a function cant just be serialized and deserialized this easily.
