nit - courtesy AI :)

let mut fields = vec![("name", "CheckoutFailed"), ("message", "Unable to process checkout.")];

for i in 1..=num_attributes {
    fields.push((format!("field{}", i).as_str(), format!("field{}", i).as_str()));
}

error!(fields.iter().map(|(k, v)| (*k, *v)).collect::<Vec<_>>());
