deleting a key inside of an object inside an array doesn't work as expected

[sebastiandeutsch]

I'm using the json from the readme:

json = <<-HERE_DOC
{"store":
  {"bicycle":
    {"price":19.95, "color":"red"},
    "book":[
      {"price":8.95, "category":"reference", "title":"Sayings of the Century", "author":"Nigel Rees"},
      {"price":12.99, "category":"fiction", "title":"Sword of Honour", "author":"Evelyn Waugh"},
      {"price":8.99, "category":"fiction", "isbn":"0-553-21311-3", "title":"Moby Dick", "author":"Herman Melville","color":"blue"},
      {"price":22.99, "category":"fiction", "isbn":"0-395-19395-8", "title":"The Lord of the Rings", "author":"Tolkien"}
    ]
  }
}
HERE_DOC

and trying to remove an attribute of an arrayobject

JsonPath.for(json).delete("$.store.book[0].category")

Unfortunately it removes the complete book object:

{"store"=>
  {"bicycle"=>{"price"=>19.95, "color"=>"red"},
   "book"=>
    [{"price"=>12.99, "category"=>"fiction", "title"=>"Sword of Honour", "author"=>"Evelyn Waugh"},
     {"price"=>8.99, "category"=>"fiction", "isbn"=>"0-553-21311-3", "title"=>"Moby Dick", "author"=>"Herman Melville", "color"=>"blue"},
     {"price"=>22.99, "category"=>"fiction", "isbn"=>"0-395-19395-8", "title"=>"The Lord of the Rings", "author"=>"Tolkien"}]}}

expected:

{"store":
  {"bicycle":
    {"price":19.95, "color":"red"},
    "book":[
      {"price":8.95, "title":"Sayings of the Century", "author":"Nigel Rees"},
      {"price":12.99, "category":"fiction", "title":"Sword of Honour", "author":"Evelyn Waugh"},
      {"price":8.99, "category":"fiction", "isbn":"0-553-21311-3", "title":"Moby Dick", "author":"Herman Melville","color":"blue"},
      {"price":22.99, "category":"fiction", "isbn":"0-395-19395-8", "title":"The Lord of the Rings", "author":"Tolkien"}
    ]
  }
}

@Skarlso any ideas?

Hello.

No idea, sorry. I haven't been a maintainer of this project for over 4 years. :D
