Error: plugin must be a function or a promise

[Jaynarol]

Title says it all - I'm trying to register the plugin in the following way, as per the docs:

fastify.register(require('fastify-cron'), {
  jobs: [
    {
      cronTime: '50 * * * *',
      onTick: someFunction,
      startWhenReady: true
    }
  ]
})

The docs use the TypeScript import style, if you want to use require, you'll need to specify the default export:

fastify.register(require('fastify-cron').default, {
  jobs: [
    {
      cronTime: '50 * * * *',
      onTick: someFunction,
      startWhenReady: true
    }
  ]
})
