Hello @sampratha28! 👋 I'm Dosu, a friendly bot here to assist you with bugs, answer your questions, and help you become a contributor while we wait for a human maintainer. Don't worry, we'll get your issue sorted out together. 😊

Based on the similar issues I found in the langflow repository, there could be a few reasons why the UI is not loading.

One of the issues, UI wont open due to javascript security error, suggests that the problem might be due to a JavaScript security error. This issue was also referenced by another issue, Blank page / broken UI, which might indicate that the problem is common.

Another issue, Blank UI page after started, was resolved by a commit that fixed a bug where a parameter of value False would be treated as null. You can check the commit here for more details.

The third issue, Blank page appears when accessing Langflow website, suggests that the problem might be due to a missing script in the assets folder.

As for the LoadingSpinner component, it seems to be returning an empty fragment (<></>), which means nothing is displayed when this component is used. You can check the code here. To fix this issue, you should return a loading spinner or some other loading indicator from this component.

Unfortunately, I couldn't find any changes in the latest version of langflow that could potentially cause the UI to get stuck on loading. It would be helpful if you could provide more details about the issue, such as any error messages you're seeing in the browser console. This would help in diagnosing the problem.

I hope this helps! If you have any more questions, feel free to ask.

I have switched to version 0.6.7 and still the error with docker-compose

`FROM python:3.11-slim

RUN apt-get update && apt-get install gcc g++ git make -y && apt-get clean
&& rm -rf /var/lib/apt/lists/* RUN useradd -m -u 1000 user

Create the directory and set the permissions

RUN mkdir -p /home/langflow && chown user:user /home/langflow USER user ENV HOME=/home/user
PATH=/home/user/.local/bin:$PATH

WORKDIR $HOME/app

COPY --chown=user . $HOME/app

RUN pip install langflow>==0.6.7 -U --user

CMD ["python", "-m", "langflow", "run", "--host", "0.0.0.0", "--port", "7862", "--log-level","debug"] `

any idea how to solve it directly in the docker image?
