@JadTawil77 Hello there! I'm here to help you with your Docker Compose issue. I'm a bot that can assist you in solving bugs, answering questions, and becoming a contributor. Let's work together to resolve the issue you're facing.

The error you're encountering, AttributeError: module 'sqlalchemy.dialects' has no attribute 'sqlite', suggests that there might be an issue with how the SQLite dialect is being imported or used in the Langflow codebase. In Langflow, the SQLite dialect is imported as follows:

from sqlalchemy.dialects import sqlite as dialect_sqlite

This import is used to check if the dbapi_connection is an instance of sqlite3.Connection or dialect_sqlite.aiosqlite.AsyncAdapt_aiosqlite_connection ^[1].

To resolve this issue, ensure that the version of SQLAlchemy being used is compatible with this import. The Langflow codebase specifies SQLAlchemy version >=2.0.36 ^[2]. Make sure your environment is using this version or a compatible one. If the issue persists, double-check the import statements and any custom configurations related to SQLAlchemy in your setup.

@dosu Since we are running a docker container, the docker image should have all the necessary packages and their compatibilities, not my native machine.

The Docker image should indeed include all necessary packages and their compatible versions. The base Docker image for Langflow is langflowai/langflow:latest ^[1]. If you're encountering issues with SQLAlchemy, it might be worth checking if the Docker image is up-to-date or if there are any known issues with the specific version of SQLAlchemy included in the image. You can try pulling the latest version of the image to ensure you have the most recent updates:

docker pull langflowai/langflow:latest

If the problem persists, it could be related to how the image is built or configured. You might want to inspect the Dockerfile or any custom configurations that could affect SQLAlchemy's behavior.

Indeed the problem does persist with the latest image.

We also observe this error after updating from the previous Docker container with an existing database.
Previously Langflow was working nicely.

@desenvolvedor-guibson-lizardo Not yet.

We shouldn't have to use an old version of langchain to make the docker work. The docker image should be up to date with latest.
I will await a fix :)

Build a Docker image from the main branch and push it to your own registry. This solved the problem for me.

Issue was fixed in this PR #4599

Waiting for a quick update in docker hub.

I am also waiting to run an instance!

Hello everyone,

This issue is related to #4572, which was resolved with PR #4599.

You can use the nightly version of Langflow as a temporary solution until the fix is included in the next official release!

• PyPI Nightly Version
• Docker Nightly Tags

For this reason, I will go ahead and close this issue.
