Default values in GraphQL input types are not supported

Hello @Andrey_Nado, are you using the Open Source product?

I tried this in a Self Managed setup but could not reproduce the issue. I have shared my schema and API definition below.

Schema

type Mutation {
  default: String
}

type Query {
  default: String
}

enum MyEnum {
  VALUE_A
  VALUE_B
}

input MyInput {
  fieldA: MyEnum!
  fieldB: String
}

input StringInput {
  field: String
}

input ReviewInput {
  stars: Int! = 5
  commentary: String
}

extend type Mutation {
  myMutation(myInput: MyInput!): Boolean
  stringMutation(string: String): String
  stringInputMutation(stringInput: StringInput!): String
  reviewInputMutation(input: ReviewInput!): String
}

    }
}

If mine doesn’t work for you then can you share your API definition file?
