"copy file: sftp: \"Failure\" (SSH_FX_FAILURE)" - Error when downloading

**Describe the bug**
Running synpod download of pgdata , the first thing it attempts to download outputs an error

appears to try to download a directory as a file?

level=ERROR msg="file download error" pid=1367 err="copy file: sftp: \"Failure\" (SSH_FX_FAILURE)"
**To Reproduce**
Steps to reproduce the behavior:

kubectl-syncpod download --namespace test1 --pvc db-s6hg-pgdata --mount-path /pgdata --src / --dst ./syncpod-pgdata/pg14 --log-level debug -w 1
(I set to 1 worker so i could try to figure out which file was triggering it)
...
time=2026-06-11T14:33:56.468-04:00 level=DEBUG msg="download file" pid=1367 remote=/pgdata/pg14/pg_wal local=syncpod-pgdata/pg14/pg14/pg_wal
time=2026-06-11T14:33:56.474-04:00 level=ERROR msg="file download error" pid=1367 err="copy file: sftp: \"Failure\" (SSH_FX_FAILURE)"
time=2026-06-11T14:33:56.475-04:00 level=DEBUG msg="download file" pid=1367 remote=/pgdata/pg14/global/pg_control local=syncpod-pgdata/pg14/pg14/global/pg_control

...
in the logs it does later recurse through pg14_wal and download files that are in that directory, but for some reason its first operation is to try to download the directory as a file, and writes errors.
