The issue is with the refs, always make sure to refer the refs to whatever name your are exporting from the models.

// Model

const Task = mongoose.model('**Tasks**', taskSchema);

//Refs

userSchema.virtual('tasks', {
ref: '**Tasks**',
localField: '_id', // field in current model
foreignField: 'owner' // corresponding field in other model

});
