We are trying to run through some of the panel-examples as standalone apps, and we are getting an error thrown when we access the page from chrome, then it shuts down with the below error.
Since we want to access from chrome and run on AWS, we have this in a container. Any advice be appreciated.
We are running panel 0.9.3 and bokeh 2.0.0
These examples all run fine from jupyterlab.
