Schema hasn't been registered for model

[mayconsilvaa]

Hi! Good morning.

I am getting the following error when working with ref.

Schema hasn't been registered for model "User". Use mongoose.model(name, schema)

--

const { ObjectId } = use('mongoose').Schema.Types

leaderId: {
type: ObjectId,
ref: 'User',
required: true,
}

Thank you to help!
