Почему возникает ошибка LookupError: Proxy is closed! в aiogram?

Пишу код

@dp.message_handler(state=FSMGotoeditcompdata.updtdatacomp)
async def get_new_comp_data(callback : types.CallbackQuery, state: FSMGotoeditcompdata):
async with state.proxy() as data:
    data['tg-id'] = callback.from_user.id
    data['userData'] = callback.text
    data['dataName'] = dataNameComp
if dataNameComp == 'line-business':
    lineBusinessInfo = dbcommon.getAllLineBusiness()
    listEmp = []
    for item in lineBusinessInfo:
        listEmp.append(item['id'])
    if int(callback.text) in listEmp:
        oneLineBusinessInfo = dbcommon.getLineBusinessById(int(callback.text))
        print(oneLineBusinessInfo)
        data['lineBusiness'] = oneLineBusinessInfo[0]['name']
        data['lineBusinessId'] = int(oneLineBusinessInfo[0]['id'])
        await dbcompanies.updtCompInfo2(state)
        await state.finish()
        await bot.send_message(callback.from_user.id, changeSuccessText2 + oneLineBusinessInfo['name'], reply_markup=editCompData_kb)
        await callback.answer()

И выдает ошибку

Task exception was never retrieved

LookupError: Proxy is closed!

Хотя выборка из базы проходит в этой строке oneLineBusinessInfo = dbcommon.getLineBusinessById(int(callback.text))
Там такое значение

[{'id': 8, 'name': 'Экономика и финансы'}]

В чем может быть дело?
