尝试使用ebaysdk-python列出项目时出现以下错误：
error, Code: 21919301, The EAN field is missing. The EAN field is missing. Please add EAN to the listing and try again.
这是完整的代码：
from ebaysdk.trading import Connection as Trading
from ebaysdk.exception import ConnectionError
try:
#api = Trading(domain='api.sandbox.ebay.com', config_file='ebay.yaml')
api = Trading(domain='api.ebay.com', config_file='ebay.yaml',debug=True)
response = api.execute('GetUser', {})
#print(response.dict())
#print(response.reply)

我在brand和MPN上遇到了相同的错误，但是我设法使用ItemSpecifics和NameValueList解决了这个错误，但是EAN field却一无所获。如您所愿，我不会穷尽所有不同的组合，但显然它们不应全部出现在代码中。
这里提出了一些类似的问题：
EBAY API EAN for Variation Listing eBay API call not working for UPC/EAN
但是没有提供有效的有效解决方案，或者至少在我的应用程序中不起作用。
