Cannot resolve "Adonis/Addons/Mail"

[prab-it]

I got an error when I try to run this code from my custom command (Debug.ts)

node ace debug

import { BaseCommand } from '@adonisjs/ace'
import Mail from '@ioc:Adonis/Addons/Mail'

export default class Debug extends BaseCommand {
  public static commandName = 'debug'
  public static description = 'Run experimental code'

  public async handle () {
    const { url } = await Mail.preview((message) => {
      message
        .to('[email protected]')
        .from('[email protected]')
        .subject('Welcome Onboard!')
        .htmlView('emails/welcome')
    })

    console.log(`Preview url: ${url}`)
  }
}

✖ fatal IocLookupException: E_IOC_LOOKUP_FAILED: Cannot resolve "Adonis/Addons/Mail" namespace from the IoC Container

Hey @prab-it! 👋

You need to change a setting in your command so Ace knows that he need to load the application.
The following code should be added directly inside your command.

public static settings = {
  loadApp: true,
}

@RomainLanz thanks! 👍

Similarly, in Adonis 6 you must do the following:

static options: CommandOptions = {
  startApp: true,
}
