I think this may be an issue from the Notion formula itself - the formula output is of unknown type (i.e., Notion canâ€™t predict exactly the data type of the formula value). It could be helpful if you share your Notion database and formula setup (if you can share a public duplicable URL it would be great) and what you intend the formula to output

Hi Simo,

here is the public link for that database

link:- Notion â€“ The all-in-one workspace for your notes, tasks, wikis, and databases.

Thank you - I see that the formula result is of â€śunknownâ€ť type in Notion indeed. The formula is incredibly long so I havenâ€™t analyzed it fully, but it seems that it uses several nested if statements, whose result is sometimes a date, sometimes a text, sometimes a boolean.

In its current state, you canâ€™t use it in Make filters because of the unknown data type - if you want to implement a quick fix and have the formula result be of type â€śstringâ€ť (which matches your selection in the screenshots attached to your post), you can add â€ś.format()â€ť to the end of the formula (screenshot 2). This should resolve the error messages in Make, although itâ€™s a â€śquick fixâ€ť because it doesnâ€™t address the data type â€śissueâ€ť in the formula itself.
