Type 'ObjectId' does not satisfy the constraint 'MongooseDocument'

I 'm trying to bind my Model with a mongoose schema using Typescript. Everything looks good except when I use ObjectId inside mongoose.Types.DocumentArray<>.

export interface TestModel extends mongoose.Document {
  name: string;
  sort: mongoose.Types.DocumentArray<mongoose.Schema.Types.ObjectId>;
}

const TestSchema = new mongoose.Schema({
  name: String,
  sort: [mongoose.Schema.Types.ObjectId]
});

export default mongoose.model<TestModel>('Test', TestSchema);

Following is the error I see

Type 'ObjectId' does not satisfy the constraint 'MongooseDocument'.
Type 'ObjectId' is missing the following properties from type 'MongooseDocument': $isDefault, $session, depopulate, equals, and 24 more.ts(2344)

If I use 

sort: [mongoose.Schema.Types.ObjectId];

instead of

sort: mongoose.Types.DocumentArray<mongoose.Schema.Types.ObjectId>;

Everything looks good on schema side but I see mongoose type errors with methods like .pull() when doing operations on the modal results (TS is not picking it up as mongoose array type.)

Scratching my head with this for hours, any help will be really appreciated.

Found the problem. I'm stupid, it's a silly mistake I was using wrong Type in type definition. Should be using mongoose.Types.Array instead of mongoose.Types.DocumentArray
