Notion error: "[400] Property is expected to be select"

How To
1

I’m trying to Map a select property in Notion:

  • there’s a form on WPForms showing a list of values to the user
  • the values have the same names as the values in the select property
  • in a “Create database item” module, I turn on “Map” on the property and pass the text field of the form as a parameter

It worked when the property was of type multi-select. Turning it into select, it returns the error in the title of this post.

The WPForm field content is of type “text”. I already mapped a state property with a text parameter in the past.
Why isn’t it working this time?

Here’s the blueprint:

The property I’m talking about is called “Equipaggiamento”.
