function main(){
    // Since order number 123 does not exist, this will trigger an error
    exchange.GetOrder("123")
    var error = GetLastError()
    Log(error)
    // Output: the error message of the failed GetOrder call
}


    python
    
    
def main():
    exchange.GetOrder("123")
    error = GetLastError()
    Log(error)
    # Output: the error message of the failed GetOrder call


    rust
    
    
fn main() {
    // Since order number 123 does not exist, this will trigger an error

    let _ = exchange.GetOrder(&id);

    Log!(error);
