Partial seems not to be supported

[Loksly]

Hi everyone!

I recently realized I cannot use Partial. For example this works:

src/services/index.ts

import { Path, POST } from "typescript-rest";
import { Response } from "typescript-rest-swagger";

export interface Complex {
    fieldC: string;
    fieldD: number;
}

export interface MyBodyDefinition {
    fieldA: string;
    fieldB: Complex;
}

@Path("/api/v1/example")
export class ExampleService {

    @Response<MyBodyDefinition>(200, "Configuration")
    @Path("update")
    @POST
    async update( body: MyBodyDefinition ): Promise<MyBodyDefinition> {
      return Promise.resolve(body);
    }  
}

But if you change MyBodyDefinition to:

export interface MyBodyDefinition {
    fieldA: string;
    fieldB: Partial<Complex>;
}

then the output is:

There was a problem resolving type of 'PartialComplex'.
There was a problem resolving type of 'MyBodyDefinition'.

For the record, the rest of the files have this content:

Thanks for your help.

It seems like none of the build-in types are supported. Same issue for union types (it's even worse - a client fallback to "{}")

Generics and Record type also give and error

Same issue here using the Pick type.
