Hi,
after running for long time OpenWebUi I can't register o login anymore,
An error "Something went wrong :/ 'AuthModel' object has no attribute 'model_dump'" pop-ups
For terminal i see:
INFO: 127.0.0.1:49949 - "POST /auths/signup HTTP/1.1" 500 Internal Server Error

I don't use Docker but manual installation.
No problem during install (npm, bun, pip) and localhost:8080 starts with no errors.
Any help?
Thank you!

ps:
I'm on a MacOS sonoma, python 3.11

Possibly tangential to the issue you're having, but why are you using signup if you already have an account? Unless you're clearing your backend/data folder each time you update you should be able to login with the account you created previously.

Hi, I accidentally threw away open-webui folder so I installed it again with these commands:

  • cloned again from here
  • I created an env file: cp -RPp .env.example .env
  • Run "bun install" and "bun run build"
  • cd in backend and "pip install -r requirements.txt"
  • sh start.sh

No problem launching open-webui, no errors on terminal on launch, it stacks on registration with an error 500
I tried also to download version 0.1.109 but same error.

Solved, it was something related to python version after macOS update (maybe command line tools update)
Using python3 venv solved auth issue.

I met the same problem: "ERROR:apps.webui.routers.chats:'ChatModel' object has no attribute 'model_dump'"
Just because i set the port "open-webui serve --port 8502", the I got that error.
First time when I excute "open-webui serve", it's ok. When I set the port, it raises errors like above.
