Hello I am new to datascript and I explore Athens codebase that uses it. Playing with datascript.core/datoms I get an error with the :avet index: #error {:message "Attribute :block/string should be marked as :db/index true", :data {:error :index-access, :index :avet, :components [:block/string]}} Where should I declare this :db/index true ?

here is my lookup (d/datoms @dsdb :avet :block/string) I tried to edit the schema here without much success https://github.com/athensresearch/athens/blob/main/src/cljs/athens/db.cljs#L126-L134

my new schema looks like this with :block/string added

@UC0JV84JF without looking at the doc's that seems reasonable, are you still getting the error?

yes, but I think it has something to do with the way the db is created on Athens side. Because in the REPL I can see the index when I do (d/empty-db schema) But the index is notthere when I inspect the schema for the datascript db that is defined here https://github.com/athensresearch/athens/blob/main/src/cljs/athens/db.cljs#L137 It must be reset somewhere else. I need to dig more.
