      Returns:
      It may return any value that is valid for a spring-graphql controller, annotated by the @SchemaMapping annotation
      Throws:
      NoSuchElementException - This method may return a NoSuchElementException exception. In this case, the exception is trapped by the calling method, and the return is consider as null. This allows to use the Optional.get() method directly, without caring of whether or not there is a value. The generated code will take care of the NoSuchElementException exception.
