Running Cassandra in Docker, container start before the database is ready

I want to create a simple cassandra db , insert some data and print all the data in the vector db
This is the structure of my exercise:

/cassandra_study
├── docker-compose.yml
├── Dockerfile
└── app.py

And that are code of the all the scripts:
Docker-compose.yml

services:
  app:
    build: 
      context: .
      dockerfile: ./Dockerfile
    volumes:
      - .:/app
    container_name: app-container
    depends_on:
      database:
        condition: service_healthy

  database:
    image: cassandra:latest
    ports:
      - 9042:9042
    container_name: cassandra-study-container
    healthcheck:
      test: ["CMD", "cqlsh", "-e", "descripe keyspace"]
      interval: 30s
      timeout: 10s
      retries: 5

Dockerfile

FROM python:3.10-slim

WORKDIR /app

RUN pip install cassandra-driver

COPY . /app

CMD ["python", "app.py"]

In this script i create the keyspace, the table and insert and print some random data. App.py

from cassandra.cluster import Cluster
from cassandra.query import SimpleStatement

def create_keyspace_and_table(session):
    keyspace_query = """
    CREATE KEYSPACE IF NOT EXISTS store WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'}
    """
    session.execute(keyspace_query)

    session.set_keyspace('store')

    create_table = """
    CREATE TABLE IF NOT EXISTS store.mytable (
        id UUID PRIMARY KEY,
        message TEXT
    )
    """
    session.execute(create_table)

def insert_data(session, message):
    insert_query = """
    INSERT INTO store.mytable (id, message) VALUES (uuid(), %s)
    """
    session.execute(insert_query, (message))

def print_data(session):
    select_query = "SELECT * FROM store.mytable"
    rows = session.execute(select_query)

    for row in rows:
        print(f"ID: {row.id}, Message: {row.mesage}")


if __name__ == "__main__":
    
    cluster = Cluster(['database']) 
    session = cluster.connect()

    try:
        create_keyspace_and_table(session)

        data = [
            ("Ciao sono il primo"),
            ("Ciao sono il secondo"),
            ("Ciao sono il terzo")
        ]

        for message in data:
            insert_data(session, message)

        print_data(session)
    finally:
        cluster.shutdown()

When i try to run the code:
The error that give me when i do docker compose up is this:

dependency failed to start: container cassandra-study-container is unhealthy

i think this error come out, because the container is starting up before the database is fully ready. Someone can give me advice how to resolve this problem

Looking on internet and doing some debug
