Flow is not opening

Flow is not opening and asking to restart langflow or report to Github

Hey @PremKumar135! 👋 I'm here to help you with any bugs, questions, or contributions while we wait for a human maintainer. Let's tackle this together!

There are a couple of similar closed issues related to the Flow application not opening. One suggested solution was to check if the issue persists on the latest version of the main branch ^[1]. Another issue titled "gui interface does not start" was closed without comments or references ^[2].

The Flow application might not be opening due to an unexpected error. The CrashErrorComponent in Langflow is designed to handle such errors by prompting you to restart Langflow or report the issue on GitHub ^[3].

Additionally, there are known issues that could cause this problem, such as having a previous version of Langflow installed or version conflicts during installation. You can try running python -m langflow run instead of langflow run, or reinstall Langflow with python -m pip install langflow --pre -U --force-reinstall ^[4]. If you encounter migration errors, clearing the cache might help ^[4].

Please give us more details.

Are you using self-hosted version, cloud version?

In my case problem was with flow build log, forgot to save front-end error message, but after clearing table "vertex_build" flow are opens again.

@carlosrcoelho i am using self-hosted version. I am running the langflow v1.1.3 and suddenly it crashed and forced me to restart or report to Github. I just closed and open it again. It worked for now. But would like to know that the root cause is addressed.

Can you share a flow that is occurring, or even detail the steps that lead to this problem?

[flefevre]

I have exactly the same problem. There is no log in the docker. If I keep on the tab that list the different flow and duplicate it I am able to open the clone

Same error here with fix
#5975

@PremKumar135
Are you still having this problem? It got fixed a couple days ago.
