> The {{@Nullable}} annotation causes a failure because the {{makeNullable(Schema)}} method assumes that the type passed in is not already a union. When it is a union, either from using {{Nullable}}, {{AvroSchema}}, or a {{Union}}-annotated type, an exception is thrown that unions can't contain unions.
