Unsupported schedme. use 'dev' mode

Im getting this error when running

vault-ssh-helper -verify-only -config /etc/vault-helper.d/config.hcl

On the client, how could i fix it? (Im not running vault on dev mode)

Please refer to the vault-ssh-helper README.md.

You will find that it is referring to dev mode for the helper, not the Vault server.

Sorry, but then, how could i fix that?
