【问题描述】：
我正在使用 python 在 IBM Cloud 中创建自定义图像。我有一个非常简单的直接代码来创建图像，但它失败了。 根据我的说法，我正在传递所有参数的相关正确详细信息。
我仍然得到一个描述性不强的错误：
ERROR:root:Please check whether the resource you are requesting exists.
Traceback (most recent call last):
File "/Users/deepali.mittal/GITHUB/dcoa/python/build/dmittal/virtual-env36/lib/python3.6/site-packages/ibm_cloud_sdk_core/base_service.py", line 246, in send
response.status_code, http_response=response)
ibm_cloud_sdk_core.api_exception.ApiException: Error: Please check whether the resource you are requesting exists., Code: 400
Process finished with exit code 0
这与 COS 中的资源缺失无关。如果在 COS 中找不到图片，则会出现不同的错误。
代码：

【问题讨论】：
-
list_images() 工作正常。
