[SOLVED] Invalid document structure: Unknown attribute: "type" when trying to create a database

Hello. I have self hosted instance running on my server and has valid endpoint and most of things are working as should. Installation is fresh install of version 1.8.0. I get error when trying to create a database ' Invalid document structure: Unknown attribute: "type"'. I tried to reinstall appwrite and also I did read docs for help and scrolled some forum posts but no help. What could cause this and how to fix?

And logs show this:

appwrite  | [Error] Timestamp: 2025-11-17T19:39:15+00:00
appwrite  | [Error] Method: POST
appwrite  | [Error] URL: /v1/tablesdb

Hi! I can help you troubleshoot this issue. This "Unknown attribute: 'type'" error when creating a database typically indicates a mismatch between your Appwrite version and the database schema, or an issue with the database migration after installation. Quick question: Did you migrate from an older Appwrite version to 1.8.0, or is this a completely fresh installation with no previous data? Also, are you seeing any errors in your Appwrite server logs (you can check with docker compose logs appwrite)?

Now that you mentioned I did upgrade from 1.7.x to 1.8.0. I rereaded docs and found out that I missed docker compose exec appwrite migrate. I did that and looks like that resolved my issue.

Great to hear the migration fixed the issue! 🎉 If you want, I can also review your full Appwrite setup to make sure everything is properly upgraded, stable, and optimized. Since you already ran into a schema mismatch once, it might be good to double-check your containers, env vars, permissions, and database consistency small things that can prevent bigger issues later.

Feel free to message me if you want me to take a look or help you with ongoing Appwrite maintenance. I’m happy to help!
