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.
