Common issues with Notion in Duaer
Common Notion node issues in Duaer: missing relation properties, toggle headings, and empty-value validation errors.
Relation property not displaying
The Notion node only shows two-way relations. In Notion, edit the relation property and turn on Show on <related database>. For a one-way relation, send a PATCH to https://api.notion.com/v1/pages/<page_id> from HTTP Request with the same Notion credential.
Create a toggle heading
The Notion node can add Heading 1 to 3 but cannot make them toggleable. Add the heading with the Notion node, then send a PATCH to https://api.notion.com/v1/blocks/<block_id> from HTTP Request (Predefined Credential Type set to your Notion credential) with body {"heading_1": {"is_toggleable": true}}, swapping heading_1 for your level.
Empty values fail validation
When a field takes its value from an earlier node and that item has no data, Notion rejects the empty or null value. Check with If first and drop the field with Edit Fields (Set), or give the expression a default.
