I'm seeing the same bug, however it totally broke all my callbacks and they don't work anymore. Furthermore the fix suggested by matpap here: Error message on the browser console when using CustomJS with args in serve mode · Issue #7970 · bokeh/bokeh · GitHub to simply remove the args parameter in the CustomJS callback is totally useless if you're passing various other Bokeh objects (such as other plot objects to be changed) and dont just want to chanhe properties of the cb_obj.
I upgraded from 0.12.15 because of the bug where the DataTable cannot be edited because of a comment Bryan made saying many bugs have been fixed for the tables since May.
Honestly this should be high priority on the bugfix issues since CustomJS callbacks are one of the maain features which makes Bokeh (imo) interesting and usable for any type of user interaction.

Thanks Bryan, the bug is not critical, I mean despite the error message everything else works. I can live with that for the moment. Is there a procedure to link this thread with the github issue?
