adonis multiple database

I have lucid monggo installed, but i have to connect with my MySQL server
so i have to connect multiple databases
primary connection is mongodb
secondary connection is mysql

but i have a problem here, i already added code in my model like this

class Order extends Model {
    static get connection () {
        return 'mysql'

but when i try, result like this:

invalid connection type

how can i fix this?
thanks a lot, youre framework very awesome and helped me

Hi @elviskudo!

Do you have mysql setup in database config file?

yes I already config in env

Got it working meanwhile?

I meant mysql part in config/database.js
