Aws copy-object api with** x-amz-copy-source-if-modified-since** parameter evaluates as false, copies data . I think aws should throw error and not copy data.
C:>fsutil file createnew 5m.txt 5242880
File C:\5m.txt is created
aws s3api put-object --bucket sb31 --key 5m --body 5m.txt
{
"ETag": ""5f363e0e58a95f06cbe9bbc662c5dfb6""
}

aws s3api copy-object --bucket sb31 --key 6m --copy-source sb31/5m --copy-source-if-modified-since 2022-07-20 (this is false evaluation, still copies data)
