Type mismatch in XTC mint function Result

[tarek-eg]

Hello, There's a mismatch in theTxReceipt of the mint function between the candid and the rust implementation In Rust it's Nat and in candid it's Nat64

candid

type MintResult = variant {
    Ok : TransactionId;
    Err: MintError;
};
type TransactionId = nat64;

Rust implementation

pub type TxReceipt = Result<Nat, TxError>;

This is causing an issue when I try to decode it using agentjs IDL.decode type mismatch: type on the wire nat, expect type nat64
