Setting the value of a checkbox property in Notion

[Rebecca_Katz]

I am having trouble with part of the following scenario. The full scenario is at the end of this post for context, but the relevant part is this:
I run a filter for [Property A in Notion (checkbox)] is false. The filter works.

But the next thing I want done is for that checkbox to be updated to true/checked. This is how I thought this would be accomplished:

Unfortunately, this generates the following error message:

I have been unable to figure out on my own how to fix this, though I’m hoping it’s a really obvious error that I’m making!

Thanks for any help!

More about the complete scenario:
Trigger: watch for new responses to a form (in Tally).
Them: search database objects in Notion to find objects where Property 1 in the form response matches Property 1 in Notion.
Next there is a filter so that step three runs only when there is only one match in the database.
Then run the filter at the top of this message, and proceed from there.

Hi Rebecca,
In the second screenshot, the “Key” fields must contain the propery name. Currently, you mapped the property value. To enter the property name, either type it manually (it’s ok if it’s always the same), or try with the map() / keys() functions.

THANK YOU!! I assumed it was something obvious that I was doing wrong; I’m glad to see I was right.
