When run knife ssh error occurs only on one node, but therefore all ok

Chef Infra (archive)
1

srvadm@shiva:~$ knife ssh "name:*example.lab" "sudo chef-client 2>&1

/dev/null; if [ $? -eq 0 ]; then echo "OK"; else echo "BAD"; fi" -i
~/.ssh/id_rsa -x sysadmin --no-host-key-verify
backup.example.lab sh: 1: Syntax error: Unterminated quoted string
backup.example.lab sh: 1: Syntax error: Unterminated quoted string
titan.example.lab OK
... OK
backup.example.lab OK
callisto.example.lab OK

Why this error occurs. Chef client updated on all machines to 11.8.2
Thank you very much answers.
