Hi,

You will not have the issue if you serve everything from the backend.

Step 1. Build the frontend (it will create a build folder)

cd open-webui
npm install
NODE_OPTIONS="--max-old-space-size=8192" npm run build

Step 2. Build backend

cd backend
conda activate open-webui
pip install -r requirements.txt -U
sh dev.sh

Step 3. Use port http://localhost:8080 (instead of 5173)

Now everthing will served using port 8080, so you will get no CORS errors.
