TypeScript error when using Buffer in schema: Buffer is missing properties subtype, toObject

[airdrummingfool]

I'm having trouble using properties of type Buffer in my ts-mongoose models. Whenever I try to assign a Buffer-type object to a property defined as Type.buffer, I get the following error:
error TS2739: Type 'Buffer' is missing the following properties from type 'Buffer': subtype, toObject

test.ts

import { createSchema, Type, typedModel } from 'ts-mongoose';

const testSchema = createSchema({
    buf: Type.buffer({required: false }),
});
const TestModel = typedModel('Test', testSchema);

const buf = Buffer.from('000102030405', 'hex');
const test = new TestModel();
test.buf = buf;

npm exec tsc:

src/test.ts:10:1 - error TS2739: Type 'Buffer' is missing the following properties from type 'Buffer': subtype, toObject

10 test.buf = buf;
   ~~~~~~~~


Found 1 error.

Go to definition of Type.buffer then you'll see all the required options to create and assign buffer to Type.buffer
