[Python] How can I index search a JSON file with different elements in Python

In this python script I am trying to randomly access one of the components in this JSON file, however I repeatedly receive a "Keyerror".

Here is the code:

import json

def genCard():
with open("cards.json", "r") as file:
cards = json.load(file)
x = random.randint(0, len(cards["cards"]) - 1)
card = cards["cards"][str(x)] ## Have also used ["cards"][x]
print(card)
return card


Here is a section of the JSON file.

{
"cards": {
"25": {
"id": 25,
"name": "Aliks",
"image": "Aliks.png",
"group": "Summer",
"atk": 6,
"def": 4,
"int": 8,
"spd": 4,
"agl": 7
},
"113": {
"id": 113,
"name": "Nichel",
"image": "PlaceHolder.png",
"group": "Summer",
"atk": 7,
"def": 5,
"int": 7,
"spd": 5,
"agl": 6
},
"27": {
"id": 27,
"name": "Arian",
"image": "PlaceHolder.png",
"group": "Summer",
"atk": 8,
"def": 6,
"int": 3,
"spd": 6,
"agl": 7
}
}
}


I simply want to pick a random card from this JSON list, any help?

Here is the error report, I am using a discord library to develop a discord application.

The above exception was the direct cause of the following exception:
