onNewDing.subscribe sends the same ding over and over

  camera.onNewDing.subscribe(ding => {
    const event =
      ding.kind === 'motion'
        ? 'Motion detected'
        : ding.kind === 'ding'
        ? 'Doorbell pressed'
        : `Video started (${ding.kind})`

    console.log(
      `${event} on ${camera.name} camera. Ding id ${
        ding.id_str
      }.  Received at ${new Date()}`
    )

Generates this on a doorbell press:

I am recording when a ding is detected using the camera.recordToFile function.

This is something you will need to filter out on your end. By calling recordToFile, you may cause a new ding to be created simply by the way that Ring has it set up. You should keep track of whether or not you are currently recording, and not call recordToFile if it is already in progress.
