Successful S3 DeleteObjects returns 0 deleted and 0 errors

[rvernica]

Describe the bug

I'm submitting DeleteObjects requests in parallel from the same EC2 instance with a list of 1,000 requests each. I verify that the request is successful and check the count of the deleted objects and the count of errors. They are both 0.

Aws::S3::Model::DeleteObjectsRequest deleteReq;
deleteReq.SetBucket(_bucket);
deleteReq.SetDelete(Aws::S3::Model::Delete().WithObjects(objList));
if (outcome.IsSuccess()) {
    const auto &result = outcome.GetResult();
    result.GetErrors().size();  // is 0
    result.GetDeleted().size(); // is 0
}

Expected Behavior

GetDeleted().size() + GetErrors.size() should equal the objList.size()

Current Behavior

GetDeleted().size() = 0
GetErrors.size() = 0
objList.size() = 1000

Reproduction Steps

Aws::S3::Model::DeleteObjectsRequest deleteReq;
deleteReq.SetBucket(_bucket);
deleteReq.SetDelete(Aws::S3::Model::Delete().WithObjects(objList));
if (outcome.IsSuccess()) {
    const auto &result = outcome.GetResult();
    result.GetErrors().size();  // is 0
    result.GetDeleted().size(); // is 0
}

Do you have the correct policy permissions that would allow you to delete those objects?

[rvernica]

Yes, the objects get deleted. The returned counts are wrong.

[jmklix]

Can you include the logs from when this request is returning 0 deleted?
