Run command returns TypeError: Seeder is not a constructor

[antonkomarev]

I've added plugin:

"plugins": [
  "add-module-exports"
]

Issue replaced with another one:

TypeError: Class constructor Seeder cannot be invoked without 'new'

I've modified preset and everything seems to work now:

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "node": "current"
        }
      }
    ]
  ],
  "plugins": [
    "add-module-exports"
  ]
}

Thank for the help @sharvit!

I don't understand difference between @babel/preset-env & @babel/env, but first one works in my case.

Thank you for submitting an issue @antonkomarev

Any chance you can supply an environment/repository that showcases the issue?
It might help in this case so I can reproduce the error.

Some directions you can try:

1. Upgrading to node-12 (AFAIK node-11 is not stable)
2. Try downgrading mongoose-data-seed version to version 2.1.1 or 2.0.1, it might give us a clue if we the new version is broke.

Thanks

I've tried to downgrade to 2.1.1 & 2.0.1 but no luck, issue is in place.

The only difference in error output in 2.0.1:

Repository where I'm trying to start using your package is proprietary, so I can't share it, but will try to create a public sandbox if there will be no solution found.

Upgrade node to v12.8.1 didn't help too.
