I have followed the new instraction for loading lcangflow on docker and I am getting the following error in the log files:

Install Missing Dependencies
The error suggests that SQLAlchemy might be missing the SQLite dialect. Try the following steps:

Step 1: Add SQLite Package in Docker
Modify your Dockerfile or requirements.txt to include:

sqlite
sqlalchemy
sqlalchemy[asyncio]
Then rebuild your Docker container:

docker-compose up --build
Step 2: Manually Install SQLite in Your Docker Container
If you already have a running container, you can install the missing dependencies inside it:

Get into the Docker container

docker exec -it <container_id> /bin/sh
You can find your container_id by running:

docker ps
Install SQLite and SQLAlchemy dialects Inside the container, run:

pip install sqlite sqlalchemy sqlalchemy[asyncio]
Restart Langflow

docker restart <container_id>
Step 3: Check Your Database URL
If you're using an .env file, make sure the database URL is correct. Open your .env file and look for something like:

DATABASE_URL=sqlite+aiosqlite:///./db.sqlite3
If it’s missing sqlite+aiosqlite, update it and restart your container:

docker-compose down && docker-compose up -d
Final Check
Once the container restarts, check the logs again:

docker logs <container_id>
