Hi everyone,
I am trying to build a flow that will check my Outlook calendar for the current day and create a task in To-Do for every meeting I have today that has no Category because I don't want to see the events I've categorized in my calendar such as Focus Time (Green Category) or Lunch (Purple Category) etc. in my To-Do's.
I've already tried typing below expressions for the Filter Query field but none of them worked:
- categories eq "[]"
- categories eq []
- "categories" eq "[]"
- "categories" eq []
- categories eq "false" (... and all other combinations with and without quotation marks)
- categories eq "Green Category" --> to see if I can retrieve events with category.
Could you please check my flow below and give feedback on how to use the Filter Query functionality?

P.S. My flow works just fine without applying Filter Query. It runs every midnight and creates To-Do's in my designated list for the current day's events but I would like to only see the events with no category, like this event:

Thanks!
