Fix wrong validation on input field with default value

[ghost]

Avoid must be defined error on an input field having a default value defined in the schema:

type Query {
    structArg(i: InputType!): Boolean!
}
input InputType {
    name: String!
    defaultName: String! = "defaultFoo"
}

With variables:

{
  "var": {
     "name": "foo"
  }
}

Before:
Error received: input: variable.defaultName must be defined

After:
No more errors received, this is the expected behavior because a default value is defined in the schema.

Thanks for the PR, it needs a test and a PR description before I can merge it.

Hi, Thanks for your review.

I've updated the description but I don't have any real test to add: I've just added a field with default value in the InputType defined in vars.graphql.

Before the patch, there was an error, and no more errors afterwards.

Which test can I add in addition?

Hi @vektah,

Hope you are well. Could you please review this PR?

Thanks

@lwc Could you create a new git tag (maybe v2.2.0?),
so that we can easily import this fix into our projects with go module?

@lwc @vektah Sorry for bothering you again,
but could you create a new git tag?
