[Raymott]

The house can then grant the visitor's wishes.

Is wishes the direct object and no indirect objects

The direct object is "the visitor's wishes". There's no indirect object.
If the sentence was:
The house can then grant the visitors wishes. OR
The house can then grant wishes to the visitors;
then "the visitors" would be an indirect object and "wishes" the direct object.
