Steps to reproduce

I used the 1.0 version of the official website, and chose to synchronize documents from Notion when creating the knowledge base. When I finished creating it, if I clicked the "Add Page" button to add a new document created by Notion again, the page would show that I was not bound to Notion and prompt an error. This is obviously a BUG, ​​and it has existed for more than a week.

✔️ Expected Behavior

Avoid errors and add new Notion documents normally

❌ Actual Behavior

Unable to add Notion document

I found some similar threads that might be relevant to your issue:

1. Knowledge from notion, when add pages error - This discussion is unsolved and was last updated on March 6, 2025 ^[1].

2. Can't connect to Notion - This discussion is also unsolved and was last updated on August 1, 2024 ^[2].

Additionally, there was a closed issue titled "[Cloud] Missing added pages when trying to add a new page to Knowledge Base with Notion integration](https://github.com/langgenius/dify/issues/4921)" which was resolved by a pull request that fixed the addition of Notion pages ^[3].

The suggested solution for a similar issue involved modifying the SQLAlchemy query to use session.scalars() instead of accessing model attributes directly from a Row object. This change resolved a 500 error without requiring any environment configuration changes ^[4].

You might want to check if the solution from the closed issue applies to your situation, especially if the error is related to SQLAlchemy query handling.
