• I changed my data ID, and finally I couldn't ack it

    def _find_item_id(self, item, search=True):
        if item is None:
            return None
        elif isinstance(item, dict) and "pqid" in item:
            return item.get("pqid")
        elif search:
            for key, value in self._unack_cache.items():
                if value is item:
                    return key
            log.warning("Can't find item in unack cache.")
        elif isinstance(item, int) or (
            isinstance(item, str) and item.isnumeric()
        ):
            return int(item)
        return None

• value is item

• value == item

• warning Can't find item in unack cache.
