Is it possible to modify the type name in a query graphql

Question

I explain my situation :)

A server/client is sending me this query :

query MultiTenancy__GraphQLAPI__FindMatchesQuery($name: String!, $email: String!, $registrationNumbers: [RegistrationNumberAttributes!]!, $phoneNumber: String,
 $birthDate: ISO8601Date) {
  collaboratorMatches(name: $name, email: $email, nationalRegistrationNumbers: $registrationNumbers, phoneNumber: $phoneNumber, birthDate: $birthDate) {
    canCreate
    matches {
      id
      name ...
  }
}

But, my graphql server doesn't recognize the query.

my query error

On my side, when I send the same request in local with playground or Altair, to make it work, I have to change $registrationNumbers Type and $birthDate Type like this :

query MultiTenancy__GraphQLAPI__FindMatchesQuery($name: String!, $email: String!, $registrationNumbers: [RegistrationNumberInput!]!, 
  $phoneNumber: String,$birthDate: DateTime!) 

Do you know how I can replace these input type names? Or if there is another solution? Or if I can create my own scalar type ISO8601Date to understand the query I receive?

Thx all :)
