Unknown order sent when using `/fapi/v1/order` and/or `/fapi/v1/openOrders`

API Futures API

There are some cases where the /fapi/v1/openOrders returns an exception "Unknown order sent." thus I can not cancel some of my open limit orders.

Sometimes this error also occur on /fapi/v1/order and doesn’t create a new limit order.

This happen on random interval and some specific pairs like HNTUSDT only while it works perfectly fine on others.
