Notion module “Search Objects” / “Create Data Source Item” – [400] body failed validation

[Whispering_Wolf_Syst]

I’m trying to connect Shopify → Notion using the new “Data Source” API.

I’ve already switched from “Database (Legacy)” to “Data Source Items”.

Database ID: 29aa620cbcc480bd84bee…

Error message:

[400] body failed validation. Fix one: body.filter.or[0].title should be defined, instead was ‘undefined’.

I’ve tried “Search Objects”, “Create Data Source Item” and “Create or Update Data Source Item” but it keeps returning undefined fields.

These are my current mappings:

• Shopify → Notion connection (WWS Verbindung)

• Title → Name (Title property)

• Preis (€) → Number (Euro)

• Kategorie → Multi Select (Product Type)

• Beschreibung → Rich Text (Description HTML)

• Bild → URL (Image source)

• Status → Select (Active / Draft)

• Erstellt am → Date

The connection is valid, API key works, and I can read the database, but it fails when writing or filtering.

Could someone confirm the correct mapping for Notion Data Source properties in the new API schema?

Or share a working example of a Shopify → Notion integration using Data Source Items?

Screenshots attached:

• Error [400] body failed validation

• Property setup view

• Data Source connection screen

Hi, could you share a screenshot of the module setup please?

For the first error (body validation failed), is it possible that the Shopify value passed to the filter was empty/null?

PS. Maybe you know, but it’s not obvious, so I am noting it: For getting a Data Source ID (instead of a DATABASE ID) in Notion, you need to open the Database (i.e., the container of data source) > open the settings menu > “Manage data sources” > three dots > copy data source ID
