the problem set involves creating a class called jar and for it to be used as a cookie jar that can have cookies added to it though deposit and then cookies removed through withdraw. the program seems to be working as expected when i run it but i cannot seem to work out why i am getting this error:

🙁 Jar’s constructor initializes a cookie jar with given capacity
expected exit code 0, not 1

import sys

class Jar:
    def __init__(self, current=0, capacity=12):
        if capacity < 1:
            raise ValueError("cannot be negative cookies")
        self._capacity = capacity


        if current < 0 or current > self.capacity:
            raise ValueError("Invalid initial number of cookies")
        self.current = current         



    def __str__(self):
        return "🍪" * self.current

    def deposit(self, n):
        jar_total = self.current + n
        if jar_total > self.capacity:
            raise ValueError ("too many cookies")
        self.current = jar_total

    def withdraw(self, n):
        jar_total = self.current - n
        if jar_total < 0:
            raise  ValueError ("not enough cookies")
        self.current = jar_total

    @property
    def capacity(self):
        return self._capacity

    @property
    def size(self):
        return self.current
    

def main():
    my_jar = Jar()
    while True:
        user_action = input("deposit of withdraw? (or exit to quit:) ").strip().lower()
        if user_action == "exit":
            print("Goodbye")
            break

        if user_action in ["deposit", "withdraw"]:
            try:
                n = int(input("how many cookies?: "))
                if user_action == "deposit":
                    my_jar.deposit(n)
                else:
                    my_jar.withdraw(n)
                print(f"current number of cookies in the jar: {my_jar.size}")
                print(my_jar)
            except ValueError as e:
                print(f"error:{e}")
        else:
            print("options are: deposit, withdraw or exit ya dam fool!")
if __name__ == "__main__":    
    main()

from jar import Jar

def test_init():
    jar = Jar()
    assert jar.current == 0
    assert jar.capacity == 12
    jar = Jar(5, 10)
    assert jar.current == 5
    assert jar.capacity == 10

def test_str():
    jar = Jar()
    assert str(jar) == ""
    jar.deposit(1)
    assert str(jar) == "🍪"
    jar.deposit(11)
    assert str(jar) == "🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪"

def test_deposit():
    jar = Jar()
    assert str(jar) == ""
    jar.deposit(1)
    assert str(jar) == "🍪"
    jar.deposit(5)
    assert str(jar) == "🍪🍪🍪🍪🍪🍪"
    jar = Jar(0, 6)
    jar.deposit(6)
    assert jar.size == 6

def test_withdraw():
    jar = Jar(12)
    assert str(jar) == "🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪"
    jar.withdraw(5)
    assert str(jar) == "🍪🍪🍪🍪🍪🍪🍪"
    jar.withdraw(7)
    assert str(jar) == ""

ive tried changing a few things around but i cannot seem to remove this error. where whould i be looking? thanks in advance!
