The target object name or target bucket name for save-as is not a valid base64 URL-encoded string. For example, the request is https://tos-tools.tos-cn-beijing.volces.com/misc/sample.png?x-tos-process=image/resize,w_100&x-tos-save-object=YWJjLnBuZw==ttttttt, and YWJjLnBuZw==ttttttt is not a valid base64 URL-encoded string.

Solution

Use Base64 URL encoding to correctly encode the target object name and target bucket name.
