Compiler incorrectly reports missing required fields

[beaumontjonathan]

Description

When checking for valid input objects, the compiler incorrectly reports that required fields are missing if they come after fields which are of the incorrect type. This makes tracking down incorrect types more difficult, especially in the case of incorrect of modified enum values.

Example

https://codesandbox.io/s/nervous-mendeleev-88r0yi?file=/client/src/App.jsx:297-325

Schema

input NewUserInput {
  name: String!
  age: String!
}

mutation {
  newUser(input: NewUserInput!): User
}

Current behaviour A (correct ✅)

Query

mutation AppMutation($name: String! $age: Float!) {
  newUser(input: { name: $name, age: $age }
}

Compiler output

[ERROR] Error in the project `default`: ✖︎ Variable was defined as type 'Float!' but used where a variable of type 'String!' is expected.

Current behaviour B (incorrect ❎)

Query
