# Fix Notion object_not_found in Duaer

When the Notion node in Duaer returns Could not find database or object_not_found, the page or database is almost always not connected to your Notion integration.
## Why Duaer cannot find the Notion database

The error reads like Could not find database with ID: … Make sure the relevant pages and databases are shared with your integration. A Notion integration sees nothing until you connect it to each page or database.

## Fix it in Duaer

1. In Notion, open the page that holds the database and select ⋯ at the top right.
2. Select Connections, search for the integration your Duaer [Notion credential](/integrations/builtin/credentials/notion.md) uses, and confirm. Connecting a parent page covers its child pages.
3. Back in Duaer, pick the database again from the list in the [Notion](/build/notion.md) node and select Execute step.

## Still failing after connecting

- Wrong ID: the database ID is the 32 characters before ?v= in the link; after ?v= is the view ID.
- A linked database: the Notion API does not support it. Connect the original database.
- Another workspace: a Notion integration only reaches the workspace it was created in.
## Questions

### Does a Duaer Notion credential reach the whole workspace?

No. Connect the Notion integration to each page or database before Duaer can read or write it; a parent page covers its children.

### Can Duaer write to a Notion linked database?

No. The Notion API does not support linked databases; select the original database in Duaer.
