var.set broken in version 0.15.4

[IgorSimic]

Following: service: var.set data: entity_id: var.hass_up value: "on"

works without any problem in version 0.15.3 but in version 0.15.4 produces error: Traceback (most recent call last): File "/srv/hass312/lib/python3.12/site-packages/homeassistant/helpers/script.py", line 501, in _async_step await getattr(self, handler)() File "/srv/hass312/lib/python3.12/site-packages/homeassistant/helpers/script.py", line 736, in _async_call_service_step response_data = await self._async_run_long_action( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/srv/hass312/lib/python3.12/site-packages/homeassistant/helpers/script.py", line 699, in _async_run_long_action return await long_task ^^^^^^^^^^^^^^^ File "/srv/hass312/lib/python3.12/site-packages/homeassistant/core.py", line 2738, in async_call response_data = await coro ^^^^^^^^^^ File "/srv/hass312/lib/python3.12/site-packages/homeassistant/core.py", line 2779, in _execute_service return await target(service_call) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/srv/hass312/lib/python3.12/site-packages/homeassistant/helpers/service.py", line 975, in entity_service_call single_response = await _handle_entity_call( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/srv/hass312/lib/python3.12/site-packages/homeassistant/helpers/service.py", line 1047, in _handle_entity_call result = await task ^^^^^^^^^^ File "/home/homeassistant/.homeassistant/custom_components/var/init.py", line 447, in async_set await self.async_write_ha_state() TypeError: object NoneType can't be used in 'await' expression

Is v0.15.5 any better?
