There seems to be an issue validating array of input-objects.

Having a simple mutation:

Mutation:
    type: object
    config:
        fields:
            testMutation:
                type: Boolean
                resolve: "@=mutation('testMutation', [args])"
                args:
                    fields:
                        type: '[TestInput]'
                        validation: cascade
TestInput:
    type: input-object
    config:
        fields:
            subField:
                type: SubTestInput
                validation: cascade

SubTestInput:
    type: input-object
    config:
        fields:
            price:
                type: Float
                validation:
                    -  Positive: ~

Then sending mutation i don't get the error i expect. The first SubTestInput is not validated.

mutation{
    testMutation(fields: [
        {
            subField: {
                price: -1
            }
        },
        {
        }
    ])
}

As the second/last TestInput does not have SubTestInput defined, validation metadata is overriden with metadata that doesn't have any constraints registered and validation for first SubTestInput is not done.

I'm not familiar with the validator component. Maybe @murtukov can look into it?

same for me, none of child validations run for array of input-object
