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

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.

You using JS?

yes commonjs

it really seems that the issue only happen on HNTUSDT, this happened many time on that pair
