Can't filter Apple Reminders Due to Missing Code/Condition

[Saekiki]

I’m working on a simple scenario to sync my Apple Reminders to my Airtable To-Do table i.e. once I create a reminder on the Apple app, Airtable automatically has the same one too. This part of the scenario works fine. I used a router for updating said synced tasks since I want that if I mark a task completed in my Reminders app, it also is marked completed in my Airtable. However, I can’t seem to filter in between a “watch iOS records” module and “search Airtable records” module for completed tasks. The general code for the filter is “isCompleted = true” but it doesn’t work since the field doesn’t exist. I can’t see any other alternative of the condition/code in the output bundles since it only shows the Priority, Title, Alarm.
