        Use this method to receive incoming updates using long polling. An Array of Update objects is returned.

        You can choose to set `error_as_empty` to `True` or `False`.
        If `error_as_empty` is set to `True`, it will log that exception as warning, and fake an empty result,
        intended for use in for loops. In case of such error (and only in such case) it contains an "exception" field.
        Ìt will look like this: `{"result": [], "exception": e}`
        This is useful if you want to use a for loop, but ignore Network related burps.

        If `error_as_empty` is set to `False` however, all `requests.RequestException` exceptions are normally raised.

        :keyword offset: (Optional)	Identifier of the first update to be returned.
                 Must be greater by one than the highest among the identifiers of previously received updates.
                 By default, updates starting with the earliest unconfirmed update are returned.
                 An update is considered confirmed as soon as :func:`get_updates` is called with
                 an offset higher than its `update_id`.

                               Defaults to 0, i.e. usual short polling.
        :type  poll_timeout: int

        :param allowed_updates: List the types of updates you want your bot to receive.
                                  For example, specify [“message”, “edited_channel_post”, “callback_query”] to only
                                  receive updates of these types. See Update for a complete list of available update
                                  types. Specify an empty list to receive all updates regardless of type (default).
                                  If not specified, the previous setting will be used. Please note that this parameter
                                  doesn't affect updates created before the call to the get_updates,
                                  so unwanted updates may be received for a short period of time.

                                  If not specified, it is set to `poll_timeout`+2.
        :type request_timeout: int

        :param delta: Wait minimal 'delta' seconds, between requests. Useful in a loop.
        :type  delta: datetime.

        :param error_as_empty: If errors which subclasses `requests.RequestException` will be logged but not raised.
                 Instead the returned DictObject will contain an "exception" field containing the exception occured,
                 the "result" field will be an empty list `[]`. Defaults to `False`.
