Rank 3: Container
when i try to do this, i get the "Attribute with the requested key already exists" error.
maybe an example of my scenario would be more helpful. think of a chats collection in a messaging system. the app has a users collection as well. so in the chats collection, there'll be two obvious attributes as sender and recipient. and both of these relationship type attributes need to point to the same collection, which is users. and this doesn't seem to be possible rn in Appwrite cloud?
