использование ABI с Nethereum для запроса смарт-контракта

Question

Я пытаюсь сделать запрос по контракту PancakeSwap (F# / Nethereum):

      let pancakeSwapAddress = "0x73feaa1eE314F8c655E354234017bE2193C9E24E"   
let abi = "[{\"inputs\":[{\"internalType\":\"contract CakeToken\",\"name\":\"_cake\",\"type\":\"address\"},{\"internalType\":\"contract

let contract = web3.Eth.GetContract(abi, pancakeSwapAddress)
let cakePerBlockFunc = contract.GetFunction("cakePerBlock")
let cakePerBlock = cakePerBlockFunc.CallAsync<int64>() |> Async.AwaitTask |> Async.RunSynchronously

и это возвращает 0

однако в JS:

Я только начал использовать Nethereum несколько часов назад, так что у меня определенно может быть что-то не так. Но мне также было интересно, может ли это быть проблемой с типом. Я попробовал "BigInteger" из библиотеки System.Numeric в качестве возвращаемого типа, но мне тоже не повезло.
