It will dump everything for sure. Here I address this by showing how to filter data properly when displaying it: https://alovak.com/2024/08/15/mastering-iso-8583-messages-wi... ```
// to make it right, let's filter the value of CVV field when we output it
filterCVV := iso8583.FilterField("8", iso8583.FilterFunc(func(in string, data field.Field) string {
if len(in) == 0 {
return in
}
return in[0:1] + strings.Repeat("*", len(in)-1)
})) // don't forget to apply default filter
filters := append(iso8583.DefaultFilters(), filterCVV) err = iso8583.Describe(requestMessage, os.Stdout, filters...)
require.NoError(t, err)
