Schemafull table allowed types

[Punie]

Hello 👋
I was wondering what are the allowed types on a SCHEMAFULL table?
I was trying to add a <future> field to such a table but got an error.

Essentially, what I am trying to do is the following:

DEFINE FIELD members ON TABLE group TYPE future VALUE <future> { <-belongs<-user };

Such a field works perfectly well on a SCHEMALESS table but when running the above query I receive the following error:
There is a problem with your request. Refer to the documentation for further information.

Edit: not that big of a deal tbh as I can just inline the future when querying as such:

SELECT name, <-belongs<-user AS members FROM group FETCH members;

But would be nice to know if that is at all feasible or not 😄

In any case, SurrealDB is amazing to use already and I can't wait to dive deeper into its capabilities in my projects 😍
