Detecting of stop polling when error in handleUpdates

Hi, I came across a situation where polling was stopped due to an error in the this.handleUpdates:

fetchUpdates () {
      ...
      .then((updates) => {
        throw new Error('Example error'); // For test
        return this.handleUpdates(updates).then(() => updates)
      })
      .catch((err) => {
        console.error('Failed to process updates.', err)
        this.polling.started = false
        this.polling.offset = 0
        return []
      })
      ...
}

If an error occurs, it is logged, the polling stops and the bot stops working. And I do not know how to detect this error in order to try to resume the polling or restart the server. The real error that I had was: error 409: Conflict: terminated by other long poll or webhook and I could not process it. Are there any ways to handle such errors?

I also like the idea with bot stopped callback. Unfortunately, I’m not sure I can find enough time in the near future. Maybe someone else can help, or I’ll try to tackle the problem a little later.
