Erroneous error message after completing a transfer task

[szipan]

Describe the bug
I have a source Aliyun OSS bucket and a destination S3 bucket. The source bucket contains 474356 objects, and the total size of the bucket is around 14TB. After a transfer task, I checked both buckets. They have the same number of objects and the data sizes. So I believe the task was in fact successful. But I still got the error message, saying 474437 objects were transferred (there was only 474356 in fact) and the task is not completed.

To Reproduce
Steps to reproduce the behavior.

Expected behavior
The task should report correct status and won't say it transfers more objects than how many objects there are indeed in the bucket.
