Not working with proengsoft/laravel-jsvalidation

[davemorris80]

We're using proengsoft/laravel-jsvalidation (v2.1 for Laravel 5.5) for form validation which is checking against our FormRequest for that form - when we include "not_throw_away" as a validator on our email, the js-validation breaks with an error:

exception:“BadMethodCallException”
file:“.....vendor/laravel/framework/src/Illuminate/Validation/Validator.php”
line:1140
message:“Method [validateNotThrowAway] does not exist.”

Any ideas?

Not sure which package is failing so have raised an issue in both.

Thanks in advance.
