I am running a bokeh application with an html as output. After updating bokeh from 1.4.0 to 2.0.0 my and changing a couple of callbacks, my output gives me an empty html. Python does not show any errors.
The errors I obtain in JS console are the following
[bokeh] – "Failed to fetch JSON from null with code 0"
Unhandled Promise Rejection: TypeError: undefined is not an object
I do not really know what to do about it. Many thanks for your help in advance!
