Futures Testnet/Demo Testing

Hello,

I am making an attempt to check my futures buying and selling script however i am getting "An unknown error occurred while processing the request." in the response. I used to be making an attempt to use - https://testnet.binancefuture.com/fapi.
Nevertheless when i attempted to put a sample commerce via binance net shopper, I came upon that the api url getting used is - https://demo.binance.com/bapi/demotrading/v1/private/future/order/place-order and the response i get is - Because of the order not being crammed instantly, the FOK order has been rejected. The order won't be recorded in the order history.

Is testnet and demo futures trading unavailable presently? In that case, can anyone present an approx date as to when it can resume. If not, please give a step clever technique to start out testing on Testnet/Demo setting

Thanks,
Ayush
