OpenSea API V2 - Неверная подпись заказа при создании листинга ⇐ Python

[Anonymous]

Я хочу создать листинг через API OpenSea с Python. У меня есть ответ: {"Ошибки": ["['' НЕДВИЖИМОСТЬ ПОДРЕБРЕНИЯ ']"] "]} . Я не мог найти и информацию в документах, что подписать. В настоящее время я подписываю параметры заказа. Вот мой код: < /p>

Inside seaport-js(SDK for javascript: https://github.com/ProjectOpenSea/seapo ... rt.ts#L386) Я обнаружил, что существует функция, чтобы подписать Data Singorder () и попытался преобразовать эту идею в Python. Вот как преобразован мной sign_order Взгляд: < /p>

Знаете ли вы, как правильно подписать заказ, который будет приемлема с помощью API OpenSea?
