How to use the @0x/json-schemas.schemas.orderBookRequestSchema function in @0x/json-schemas

public async getOrderbookAsync(
        request: OrderbookRequest,
        requestOpts?: RequestOpts & PagedRequestOpts,
    ): Promise {
        assert.doesConformToSchema('request', request, schemas.orderBookRequestSchema);
        if (requestOpts !== undefined) {
            assert.doesConformToSchema('requestOpts', requestOpts, schemas.pagedRequestOptsSchema);
            assert.doesConformToSchema('requestOpts', requestOpts, schemas.requestOptsSchema);
        }
        const httpRequestOpts = {
            params: _.defaults({}, request, requestOpts),
        };
        const responseJson = await this._requestAsync('/orderbook', HttpRequestType.Get, httpRequestOpts);
        const orderbook = relayerResponseJsonParsers.parseOrderbookResponseJson(responseJson);
        return orderbook;
    }
