streamlit.runtime.caching.storage.cache_storage_protocol.CacheStorageKeyNotFoundError: Key not found in mem cache

JuanFran928 · October 1, 2023, 4:02pm

Hello, I’m having a caché error while deploying to streamlit an app using selenium, locally it works and deployed sometimes it works and sometimes dont, for me it’s hard to reproduce and debug this locally. This are the logs:

This is my app url:

this is my app github repo:

All help would be appreciated

At least a part of the problem lies here:

try:
    total_records = len(max(forecast.items(), key=lambda item: len(item[1]))[1])
except Exception as e:
    st.write("QUEEE FUEE")
    st.write(url)
    st.write(index)
forecast["spot_name"] = self.parse_spot_names(soup, total_records)

Eating exceptions like that will make you have a lot of fun trying to debug issues where the try part fails. Besides, total_records is undefined when that happens, causing even more issues.

JuanFran928 · October 2, 2023, 3:20pm

I think for some reason the selenium (through a browser) sometimes does not load the page correctly, and forecast is an empty dictionary, so when the forecast is empty i’ll put total_records = 0, while I try to debug why the browser does not render correctly the page.
Thanks
