Python code with Shopify pagination stops midway

I have this code where I want to get the Id and the Inventory item Id of all my products.
The problem is that when it arrives at 2000 products aprox it stops iterating the pagination. I don’t know if it’s a cap of the API or my code isn’t ok.

import requests
import csv

API_KEY = "key"
PASSWORD = "password"
SHOP_HANDLE = "name"
API_VERSION = '2023-07'  # Actualiza la versión de la API si es necesario
CSV_FILE_PATH = 'product_inventory_item_ids.csv'

def get_all_products():
    page_info = None
    all_products = []

    while True:
        url = f"https://{SHOP_HANDLE}.myshopify.com/admin/api/{API_VERSION}/products.json?limit=250"
        if page_info:
            url += f"&page_info={page_info}"

        response = requests.get(url, auth=(API_KEY, PASSWORD))

        if response.status_code != 200:
            print(f'Error al obtener productos: {response.text}')
            break

        products_data = response.json()

        if not products_data['products']:
            break

        all_products.extend(products_data['products'])
        page_info = products_data.get('next_page_info')

        if not page_info:
            break

    return all_products

def main():
    with open(CSV_FILE_PATH, 'w', newline='') as csv_file:
        csv_writer = csv.writer(csv_file)
        csv_writer.writerow(['Product ID', 'Inventory Item ID'])  # Encabezados del archivo CSV
        
        for product in get_all_products():
            product_id = product['id']
            inventory_item_id = product['variants'][0]['inventory_item_id']

            csv_writer.writerow([product_id, inventory_item_id])

    print('Proceso completado. Los datos se han guardado en el archivo CSV.')

if __name__ == "__main__":
    main()

I managed to use the pagination to get those 2000 products but it stops there and I just don’t know why.
