Python API 脚本为 eBay 变体返回不正确的库存值

Question

我正在尝试使用 python 脚本从有变化的 eBay 商品中读取数量。

清单是： https://www.ebay.co.uk/itm/255827467839 并且有 5 个变体，剩余数量为 3,5,5,0,1

运行以下脚本会返回变体，但数量不正确。

from ebaysdk.trading import Connection

# Replace these with your own credentials
dev_id = 'YOUR_DEV_ID'
app_id = 'YOUR_APP_ID'
cert_id = 'YOUR_CERT_ID'
token = 'YOUR_AUTH_TOKEN'

# Replace this with the item ID you want to retrieve stock for
item_id = 'YOUR_ITEM_ID'

# Create a connection to the eBay Trading API
api = Connection(
    domain='api.ebay.com',
    config_file=None,
    appid=app_id,
    devid=dev_id,
    certid=cert_id,
    token=token,
    siteid='0',  # Site ID 0 is for the US site
    https=True,
)

# Call the GetItem API to retrieve information about the item
response = api.execute('GetItem', {'ItemID': item_id})

# Extract the variations and their quantities from the response
variations = response.reply.Item.Variations.Variation
for variation in variations:
    print('Variation:', variation.SKU)
    print('Quantity:', variation.Quantity)

返回的结果为：

Variation: 2mm
Quantity: 21
Variation: 3mm
Quantity: 29
Variation: 2.5mm
Quantity: 29
Variation: 1.5mm
Quantity: 20
Variation: 3.5mm
Quantity: 9

这些随机数量是从哪里来的？？
