Hey, I'm trying to follow this set of docs to set up sticky bucketing for both the frontend and backend of a Next.js app router project. I've followed the implementation example for Next.js app router here. Is there a sticky bucket service that I should be using in this case? The

ExpressCookieStickyBucketService

doesn't seem to be compatible in this context. Appreciate any guidance!

Hi there. I am assuming you're talking about client side tests based on the link you sent. In this case, you could either use the standard

BrowserCookieStickyBucketService

or

LocalStorageStickyBucketService

. If you need to do back-end controller-level testing as well, the two Cookie-related sticky bucket services are interoperable.
