Mongoose '.inlcudes' - Argument of type 'ObjectId' is not assignable to parameter of type '{ type: ObjectId; required: true; }'

I'm in the process of converting my JS node/express & mongoose server over to Typescript, and I have an issue with mongoose's array includes method with typescript:

Argument of type 'ObjectId' is not assignable to parameter of type '{ type: ObjectId; required: true; }'.
  Type 'ObjectId' is missing the following properties from type '{ type: ObjectId; required: true; }': type, required

78     if (!building.actors.includes(mongoose.Types.ObjectId(userID)))

The line causing this issue is below:

const transformedUserID = mongoose.Types.ObjectId(userID)
if (transformedUserID && !building.actors.includes(transformedUserID)) {
   ...

The error says that the required property is missing, so I thought maybe it was an issue involving userID possibly being null, so I tried this with no success:

transformedUserID || mongoose.Types.ObjectId()

I'm new to Typescript so am not really sure why this is happening, it worked perfectly fine in plain JS. Any help would be appreciated.

Thanks

Worked out what the issue was - I was using mongoose.Schema.Types.ObjectId in my typescript interface for the Buildings model, instead of mongoose.Types.ObjectId.
