[fast-runner]

Что случилось?

Ищу купоны по облигации RU000A105FS4.
Вызовы с одинаковыми параметрами могут вернуть... разные результат.

Тинькофф API обычно возвращает ошибочное количество - 2 купона. Может потребоваться несколько запусков для получения хотя бы одного правильного ответа - 5 купонов.

Аналогична проблема с облигацией ticker 'RU000A0ZYCZ4'.

API возвращает только один купон. Финальный купон потерян в недрах backend.

[Coupon(figi='BBG00HZ418L3', coupon_date=datetime.datetime(2023, 8, 3, 0, 0, tzinfo=datetime.timezone.utc), coupon_number=23, fix_date=datetime.datetime(2023, 8, 2, 0, 0, tzinfo=datetime.timezone.utc), pay_one_bond=MoneyValue(currency='rub', units=7, nano=980000000), coupon_type=<CouponType.COUPON_TYPE_CONSTANT: 1>, coupon_start_date=datetime.datetime(2023, 5, 4, 0, 0, tzinfo=datetime.timezone.utc), coupon_end_date=datetime.datetime(2023, 8, 3, 0, 0, tzinfo=datetime.timezone.utc), coupon_period=91)]

[fast-runner]

Выявлено место ошибки.

Баг активно проявляется если использовать вызов client.instruments.get_bond_coupons(figi=bond.figi, from_=today, to=maturity_date).

Если делать вызов client.instruments.get_bond_coupons(figi=bond.figi) то возвращаются все купоны.
Ошибка связана с фильтрацией купонов по from_ to
