  1. Share the Streamlit and Python versions.
    Python 3.9
    Streamlit 1.40

I’ve seen this topic in a few different threads but am not 100% convinced that there has been a proper resolution as the only solution wasn’t confirmed that it worked. This app works extremely well with a single user but as soon as multiple instances are spun up the plotting throws this error. Not clear what exactly is causing it.

Any help is greatly appreciated. :slight_smile:

Updated the streamlit version to 1.43 and it appears to not throw the error anymore. The graph goes blank temporarily and then comes back later. I’d like to understand a bit better on what is going on under the hood here.
