Get_state() doesn't work in version 2024.4.0

I build an addon in HA with python code and much usage of get_state()

I have the problem reduced to a simple piece of testcode:

import hassapi as hass
from requests import get


class TestWM(hass.Hass):
    def __init__(self):
        self.hassurl = "http://192.168.178.80:8123/"
        self.hasstoken = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJmNmUwNjRhZmM0NTM0MDI5YmNjNzU2MDkzMTc3MmQ1NyIsImlhdCI6MTcxMjIzOTUxNiwiZXhwIjoyMDI3NTk5NTE2fQ.2sO0bo3gS81-7hW6CTDf5goQEavzdEUO7SImOb-UCu4"
        super().__init__(hassurl=self.hassurl, token=self.hasstoken)
        headers = {
            "Authorization": "Bearer " + self.hasstoken,
            "content-type": "application/json",
        }
        resp = get(self.hassurl + "api/config", headers=headers)
        print(resp.text)

    def test(self):
        state = self.get_state("input_datetime.start_window").state
        print(state)


test_wm = TestWM()
test_wm.test()

When I run this code against an HA machine with version 2024.3.3: no problems
But when I run with a machine with version 2404.4.0 I get this error:

Traceback (most recent call last):

TypeError: State.__init__() got an unexpected keyword argument 'last_reported'

I have read the release notes but only found some information about a new attribute “last_reported”.

What am I doing wrong?

You need the latest version of hassapi which has been released (after you posted this issue)
