how to add a predicate to ofType

[dbclkclk]

I've try doing

1. ow.array.ofType((val) => { .... });
2. ow.array.validate({validator: (val) => {} }

It always throws an error related to the parameter being sent to my callbacks. Thoughts?

You need to pass in a valid validator, e.g. ow.array.ofType(ow.string). It would be helpful to see your implementation of the callback if that isn't to your needs.
