Steps to Reproduce

Use the schema I sent you in the mail https://github.com/wundergraph/cosmo/issues/959#issuecomment-2258868305

Run Query:

query MutationsSchema {
  __schema {
    mutationType {
      fields {
        description
        name
        type {
          ofType {
            name
            fields {
              name
              description
            }
          }
        }
      }
    }
  }
}
