Can't disable cache for RESTDataSource

[lmx2k5]

RESTDataSource seems to cache everything and I cant figure out how to disable caching. For example I set up project which uses https://www.uuidgenerator.net/api/version4 service to generate UUID and grapqhl query always returns same UUID. This service returns header "Cache-Control: max-age=0, private, must-revalidate" so I guess responses should not be cached. I also tried to set ttl to 1 , but no effect

export class UUIDDatasource extends RESTDataSource {
	constructor() {
		super();
		this.baseURL = "https://www.uuidgenerator.net/api/version4";
	}

	async uuid() {
		return this.get('', null, {cacheOptions:{ttl:1}});
	}
}

I created sample project https://github.com/lmx2k5/rest-datasource-cache-test

oh well, I found this issue #1511 and looks like I incorrectly configured datasources property in server.
