Hi, I wrote to the chapter, they have a staff change and then test & switch to the new system: Simplifying the Chapter endpoint deployment
As a note: this system makes it easier to replicate the endpoint setup locally, but the collection has to be created once, which might be 1 or 2 hour work to get it right. But you could try it, if it is urgent. Maybe simply replacing de or en with ja in the query might do the trick, if luck is on your side.
