Hello today I've found this issue when WP_REST_Posts_Controller->get_items() returned an WP_Error object but ACF_To_REST_API_Controller->get_items() didn't handle it. This can be reproduced when you exceed total posts in WP_REST_Posts_Controller line 351 for WP version 5.5.1. I think this issue is reproducible on older versions too.
So I've made a quick fix to handle WP_Error object to prevent breaking of the API.
