Problem description

An invalid value is specified for the contrast parameter in a legacy image processing request.

Problem cause

The value of the contrast parameter is outside the valid range.

Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Fri, 03 Feb 2023 03:41:49 GMT
Content-Type: application/xml

In the request, the value 200 for the `contrast` parameter `d` is invalid, which causes the error.
