As explained it doesn't make sense to use `@once` with TimeDeltaSensor. Note that the sensor calculates `execution_date + schedule_interval` when you set `schedule_interval="@once"` there is no interval (so it's None) which is exactly what the error message says: `TypeError: unsupported operand type(s) for +=: 'NoneType' and 'datetime.timedelta'` -- This is an automated message from the Apache Git Service.
