Issue

I'm trying to migrate a project to use official typescript inferred schema definitions. One of the things I do is reuse common schema definitions. For example:

export const reusableFields = {
  description: { type: String, required: true },
  skills: { type: [Schema.Types.ObjectId], ref: "Skill", default: [] }
} as const;

export const firstSchema = new Schema({
  ...reusableFields,
  anotherField: String
})

export type Props = InferSchemaType<typeof firstSchema>;

Props typ is:

type Props = {
    description: string;
    skills: {
        1: unknown;
        0?: Types.ObjectId;
    };
    anotherField?: string;
}

Non-array types work as expected (description), but array types (skills) cannot be inferred. I haven't figured out how to make it work yet. Any suggestions?
