易趣Python查找API中的身份验证错误

我正在尝试使用ebay.yaml文件快速将我的应用程序密钥（特别是我的应用程序id）传递到查找API中。但是，即使文件与程序位于同一目录中，每次运行程序时都会引发此异常：

如果我将config_file设置为None，并将我的app id显式地传递到appid参数中，程序就会工作。ebay.yaml只是没有被正确识别。

以下内容适合我：

from ebaysdk.finding import Connection as Finding

yaml_path='C:/Users/Public/ebay/eBay_API/ebay_1.yaml' #path: yaml file location
api = Finding(config_file=yaml_path, siteid='EBAY-US')
request = {
    'keywords': 'buffalo nickel coin',
    'itemFilter': [
        {'name': 'condition', 'value': 'new'}
    ],
    'paginationInput': {
        'entriesPerPage': 10,
        'pageNumber': 1
    },
    'sortOrder': 'PricePlusShippingLowest'
}
response = api.execute('findItemsByKeywords', request)
print(response.reply.paginationOutput)

// {'pageNumber'：'1'，'EntriesPage'：'10'，'totalPages'：'982'，'totalEntries'：'9813'}
