Как исправить Unresolved reference?

код:

time_techno = mas_techno['items'][0]['date']

while True:
    def get_posts(owner_id, count, offset):
        connect = sqlite3.connect('users.db')
        cursor = connect.cursor()
        cursor.execute(f'SELECT id FROM login_id')
        ids = cursor.fetchall()
        for user_id2 in ids:
            cursor.execute(f'SELECT techno FROM login_id WHERE id = {user_id2}')
            techno2 = cursor.fetchone()
            a = techno2[0]
            if a == 'ON':

                number = 0
                mas_techno1 = vk_api.wall.get(owner_id=-210998761, v=5.131, count=1, offset=number)
                time_techno1 = mas_techno1['items'][0]['date']
                time_techno2 = time_techno1
                while time_techno1 != time_techno:  #тут ошибка
                    number = number + 1
                    mas_techno1 = vk_api.wall.get(owner_id=-210998761, v=5.131, count=1, offset=number)
                    time_techno1 = mas_techno1['items'][0]['date']
                    score = score + 1
                time_techno = time_techno2

в таком виде код выдаёт ошибку: Unresolved reference 'time_techno' как это иправить?
