Different behavior between self hosted and cloud regarding querying relationship attributes

I am wondering, what is true:

Here is stated, that queries of relationship attributes are not supported: https://appwrite.io/threads/1248091621074141214 https://github.com/appwrite/appwrite/discussions/7369 https://appwrite.io/docs/products/databases/relationships#queries

But I am using it since many month with appwrite cloud, and just realized that it is not working on my local machine using the self hosted version 1.6.0

Could you give an answer, what is the difference between cloud and self hosted regarding quering relationship attributes?

Example: One Module can have many Autonomylevels:

Modules [1] - [n] Autonomylevels

The same request causes different results on cloud an self hosted (V1.6.0):

Cloud: Request: https://cloud.appwrite.io/v1/databases/kicd/collections/autonomylevels/documents?queries%5B0%5D=equal%28%22modules%22%2C+%5B%2266130338758f1195f7cc%22%5D%29&queries%5B1%5D=orderDesc%28%22%24createdAt%22%29&queries%5B2%5D=limit%2810%29 queries[0]: equal("modules", ["66130338758f1195f7cc"]) queries[1]: orderDesc("$createdAt") queries[2]: limit(10) -> Response: 200 OK: works fine! 🙂

Local: Request: http://localhost/v1/databases/kicd/collections/autonomylevels/documents?queries%5B0%5D=equal%28%22modules%22%2C+%5B%22678841302ad6c9faa883%22%5D%29&queries%5B1%5D=orderDesc%28%22%24createdAt%22%29&queries%5B2%5D=limit%2810%29 queries[0]: equal("modules", ["678841302ad6c9faa883"]) queries[1]: orderDesc("$createdAt") queries[2]: limit(10) -> Response: 400 (Bad Request) Error: Cannot query on virtual relationship attribute
