When I try to save the environment with the alias vbox it gives Missing PEM block

Ushani Balasooriya

bosh -e alias-env vbox --ca-cert vbox/creds.yml

Validating Director connection config:
Parsing certificate 1: Missing PEM block

Exit code 1

Please explain me the below command. What is the --path parameter? I do not have a director_ssl folder. Also Is my above command correct? I have a folder called vox and creds.yml inside it.
bosh -e alias-env vbox --ca-cert <(bosh int vbox/creds.yml --path /director_ssl/ca)
