Starting all from Docker image fails

[tacass]

Describe the bug This is really two different issues, but I'll put them both here. To get the dockerized app to start I had to make this change in v1.0.0a23

I'm not an expert in asyncio in this context, but to allow it to run I made this change:

Hey @tacass Thanks for this! The asyncio problem is that when running using uvicorn directly we need to pass --loop asyncio because of the nest_asyncio.

Now, if you just want to run Langflow in a docker container, you should use the logspace/langflow:1.0-alpha image.

If you want to build the docker image yourself, you should probably use langflow.main:create_app instead of thesrc.backend....

The Dockerfiles in the root folder are still in need of updates, that's why they don't work.

You can take a look in the docker_example folder for some more up-to-date examples.

Would you be willing to test this PR out? #1751

[tacass]

I won't be able to do it today, but I can take a look at it tomorrow. Did you intend to include -loop asyncio in the uvicorn launch in the docker version?

It seems not working yet.

backend-1 | Error: Invalid value for '--loop': 'asyncio,' is not one of 'auto', 'asyncio', 'uvloop'.

I'm taking a look but there is a lot of Dockerfiles!

anyone solved the issue with docker compose for the whole stuff?

Hello @qwaszaq, Sorry for the delay. Did you try using the new version? Does the error still persist?
