Validation fails on variables used in fragments.

[todesstoss]

Hello, my query validation fails with error message:
Variable "$variableName" is never used in operation "OperationName",
while "$variableName" is used in this operation, but located in fragment which is imported from another file.

import fieldsFragment from './fragment'

const Query = gql`
  query OperationName($variableName: String!) {
    fileld {
      ...fragmentName
    }
  }
  ${fieldsFragment}
