Why Am I Receiving a 404 'object_not_found' Error in the Notion API?

Why do I get a 404 error from the Notion API despite properly linking my integration and database? I double-checked the token, yet the problem remains.

I have encountered a similar situation before and found that determining the root cause of a 404 error can sometimes be more subtle than just ensuring the token is correct. I eventually discovered that the error was related to permissions on the database side; even though the integration was properly connected, the specific access rights were not fully enabled for all necessary endpoints. It helped to re-examine all the permissions and ensure that every access scope was correctly configured. This approach saved me a lot of time trying to find other less obvious issues.
