copy object rewind gives error unable to validate source

[LadMartin]

I needed to roll-back an object foo. I tried to call cp with --rewind which resulted in an error. From documentation of the flag I would suspect that something like this should be possible --rewind value roll back object(s) to current version at specified time

Expected behavior

mc cp --rewind 1s s3/mlad-test/foo s3/mlad-test-2/ shall rollback to version of foo older than 1s

Interestingly enough, it works in combination with --recursive when setting the SOURCE as bucket

$ mc cp  --rewind 1s --recursive s3/mlad-test/ s3/mlad-test-2/
`s3/mlad-test/foo` -> `s3/mlad-test-2/foo`

Actual behavior

$ mc cp  --rewind 1s s3/mlad-test/foo s3/mlad-test-2/
mc: <ERROR> Unable to validate source `s3/mlad-test/foo`.

Steps to reproduce the behavior

mc mb s3/mlad-test
mc mb s3/mlad-test-2
touch foo
mc cp foo s3/mlad-test
mc version enable s3/mlad-test
mc cp foo s3/mlad-test/foo
mc ls --versions s3/mlad-test/foo

mc --version

mc version RELEASE.2022-05-09T04-08-26Z

System information

I am using docker version of the the mc command. The endpoint is Amazon AWS.

Please provide outputs for the each of the command that you ran, and also provide --debug output for the mc cp command.
