Amplify AppSync - List size cannot exceed 1000

Hello everyone, I'm using Amplify together with Flutter, and I've reached a point where I've been having a problem that I can't solve. It turns out that when starting the app, appSync tries to make the query, but in a specific model it seems to return more than 1000 items (List size cannot exceed 1000).

It is not possible to page the result or use query conditions, because it is an automatic process and I cannot edit the way it works. Does anyone know a solution for this to work?
