does anyone know why when using lldap-cli is returns the following error message:

Unknown field \addUserAttribute\ on type \Mutation\

when doing command `./lldap-cli schema attribute user add vpnpassword string -v -e`; the env url, admin, password are all setup and i tested with wrong ones to make sure

./lldap-cli schema attribute user list

yields a weirder message: ./lldap-cli: line 620: column: command not found
