Issue: Mapping a Notion multi-select field from Tally via Make

Hi everyone,

I’m stuck on an issue I haven’t been able to solve despite several attempts. I’m trying to automatically save responses from a Tally form into a Notion database using a Make scenario.

:backhand_index_pointing_right: In Tally, I have a multiple-choice question. The response comes through as a simple array of strings (["Forceps", "Ventouse"]).
:backhand_index_pointing_right: In Notion, the corresponding field is a multi_select property.

I understand that Notion expects the data to be formatted like this:

[
  { "name": "Forceps" },
  { "name": "Ventouse" }
]

I’ve tried several ways in Make to convert the array from Tally into the required object array format for Notion, but none of them worked. I keep getting an error during the database creation step, saying the Instrumentation property is expected to be of type multi_select.

:camera_with_flash: I’ve attached screenshots showing:

What would be the correct way to convert a simple array into the proper object array format expected by Notion in this context?

Thanks a lot for your help :folded_hands:

Hi, based on my test, you can directly map the simple array as is, without any “map” or other transformations

Hi Simo, thanks for your reply :folded_hands:

Unfortunately, I tried passing the simple array directly into the Notion module (Create a database item), and it doesn’t work in my case. I still get the error saying the field must be of type multi_select.

Just to clarify: I mocked the first module using a Parse JSON module to simulate the response from a Tally form submission, so the array structure should be identical to a real Tally response.

Here are a couple of screenshots showing:

  • the raw array I’m sending to Notion,
  • and the error returned by Make during execution.

If you have any idea how to properly format it to match Notion’s expectations, I’d love your help!

Thanks again :blush:

Appreciate all the details - one thing I would try before troubleshooting further: can you refresh the “Create database item” module (from the three dots at the top right in the module configuration) and try again?
