Hello all!

I am a Python developer exploring Bokeh JS capabilities so apologies in advance if I mistaken in something very basic.

Copy & pasted the [minimal example](https://docs.bokeh.org/en/2.2.3/docs/user_guide/bokehjs.html?highlight=javascript%20development#minimal-example) and attempted to open with chrome browser.

1. I had to remove the “integrity” and “crossorigin” to load the libraries.
2. After performing step 1 I get the following error:  
Uncaught (in promise) TypeError: Cannot read property ‘classList’ of null  
at r (bokeh-2.2.3.min.js:572)  
at Object.t.add\_document\_standalone (bokeh-2.2.3.min.js:572)  
at Object.r.show (bokeh-api-2.2.3.min.js:51)  
at html\_bokeh.html:36

Thank you for the help!

The example is indeed wrong. You can fix it locally by moving the whole last script tag inside the `body`.
