Current behavior

We have a NestJS application which uses @nestjs/schedule, version 2.1.0. For deployment we use Docker images. For almost all of our deployments it works just fine. One of the client reported though, that on their onprem, the app stopped with the following error:

We have multiple @Cron annotations in our codebase, but all looks the same:

@Cron(CronExpression.EVERY_5_SECONDS, { name: DEVICE_REGISTRATION_CRON_NAME })
async exampleCron(): Promise<void> {
  this.schedulerRegistry.getCronJob(DEVICE_REGISTRATION_CRON_NAME).stop();
  try {
    // ... code that may fail, and we must not run other iteration till it finishes
  } finally {
    this.schedulerRegistry.getCronJob(DEVICE_REGISTRATION_CRON_NAME).start();
  }
}

I searched for this error, and found some similar at https://github.com/kelektiv/node-cron/issues, but those are not same, but I would say, very similar, and relates to the same bug.

What can I do? What the NestJS team will do?

I would expect even if the cron fails, it would not stop the whole application.

@Techevan please provide some project that reproduces that issue.

[crypto-jianyong]

@micalevisk https://stackblitz.com/edit/nestjs-typescript-starter-apu3jw?file=README.md You can see that toDate and format are undefined.
