Problem with modules on forman

Hello'

my main problem with moving to forman is with modules that used to work on
my puppet server and some don't even install on the forman server and other
dosn't like the manifest
I understend that the syntex
:: is problematic
is there a known solution ?

for example i have a zabbix module that works on my puppet and on the

class { 'apache':
mpm_module => 'prefork',
}

class { 'postgresql::server': }

    class { 'mysql::server': }

    class { 'zabbix':
    zabbix_url    => 'zabbix.example.com',
    database_type => 'mysql',

}

the error is , cannot find declered class zabbix

Thanks in advance for any input
