With a schema like the following I get the error that ReferenceSportsClassInput is not of type GraphQLInputType, but it clearly is.

Debugging into com.coxautodev.graphql.tools.SchemaParser shows, that ReferenceSportsClassInput is listed in scanResult.unusedDefinitions and not in scanResult.definitions .

Referencing ReferenceSportsClassInput in another input directly (not as List) fixes the problem for the list-reference.

Schema:

type Mutation {
    createPerson(input: CreatePersonInput!): Person!
}

type Person {
    id: ID!
    firstName: String!
    name: String!
    displayName: String!
    birthDate: String!
    emailAddress: String!
    phoneNumber: String
    postalAddress: PostalAddress!
    sportsClasses(page:Int! = 0, pageSize: Int! = 50): SportsClassPage!
}

input CreatePersonInput {
    firstName: String!
    name: String!
    displayName: String!
    birthDate: String!
    emailAddress: String!
    phoneNumber: String
    postalAddress: PostalAddressInput!
    sportsClasses: [ReferenceSportsClassInput!]
}

input ReferenceSportsClassInput {
    id: ID!
}
[...]

Exception:

Caused by: com.coxautodev.graphql.tools.SchemaError: Expected type 'ReferenceSportsClassInput' to be a GraphQLInputType, but it wasn't!  Was a type only permitted for object types incorrectly used as an input type, or vice-versa?

Same issue, tools v. 5.6.1. @nidomiro , have you found a solution?

Unfortunately not. My workaround is to create a dummy-Query and reference the type here explicitly.
