Hello, I am currently in the process of moving from cockpit v1 to v2 and it appears that I’m not able anymore to filter on a field from a collection link. In the v1 I was able to do filter[myCollection.myField] = value but now when I do filter={“myCollection.myField”:value} or filter={myCollection:{myField:value}} it always returns a 404 even when it should not. Am I missing something?
