PermissionError: [Errno 13] when using streamlit_timeline on Streamlit Cloud

No problems when running locally but when I try on the Community Cloud I get this error:

streamlit.runtime.caching.cache_errors.CacheKeyNotFoundError: Local disk cache storage is disabled (persist=None)

During handling of the above exception, another exception occurred:

PermissionError: [Errno 13] Permission denied: '/home/adminuser/venv/lib/python3.9/site-packages/streamlit_timeline/frontend/build/index.html'

It happens with just instantiating a basic timeline like this:

import streamlit as st
from streamlit_timeline import st_timeline


st.write("## Timeline")

doc_data = [
    {
        "id": 1,
        "content": "item 1",
        "start": "2021-01-01",
        "end": "2021-01-02",
    }
]

timeline = st_timeline(doc_data, groups=[])  # , options=timeline_options)

Is there a server setting I’m missing?

Thanks!

Hey @makrtank ,

Thanks for sharing this question!

I’m assuming streamlit_timeline is included in your requirements file?

Hey @Caroline

Mild panic as I double checked… :sweat_smile:

it’s actually the streamlit-vis-timeline project:
streamlit-vis-timeline==0.3.0

That makes more sense given where the exception is thrown. But still not sure why it has a problem there.

Just deployed it to AWS EC2 and it works there…

Hm, that is peculiar – can you share the link to the deployed app?

It looks like the streamlit_timeline is doing something a bit unusual, in that it attempts to dynamically overwrite files when the component is actually used. You might consider actually filing an issue with streamlit-timeline requesting that they not require overwriting of files this way, as it seems a bit strange to require this when actually running the code.
