I have this created command called 'newsletter'. When I call 'adonis newsletter' on local, it works just fine. But when I try to run with scheduler on plesk with 'cd httpdocs; node ace newsletter', it was completed with this error:

/var/www/vhosts/mydomain.com/httpdocs/node_modules/@adonisjs/ignitor/src/Ignitor/index.js:286
async _bootProviders () {
