UnsetValueError while plotting WordCloud using bokeh package

Question

Here is the code I am using to generate a word cloud using bokeh library in python. The current python, bokeh, and bokeh_wordcloud2 version(s) are 3.7.6, 1.4.0, and 0.9 respectively.

from bokeh.io import show
from bokeh.models import ColumnDataSource
from bokeh_wordcloud2 import WordCloud2

data = [['susan',6], ['tom',3], ['frankie',8],
        ['roger',7], ['amy',9], ['nicole',10],
        ['joran',5], ['mark',4], ['brianne',7],
        ['michael',8], ['greg',4], ['adrian',6], ['drew',9]]
names,weights = zip(*data)
test1 = ColumnDataSource({'names':names,'weights':weights})
wordcloud = WordCloud2(source=test1,wordCol="names",sizeCol="weights",color="pink")
show(wordcloud)

Error

UnsetValueError: WordCloud2(id='1002', ...).click doesn't have a value set

I see that click is expecting a JS Instance for input ==> click: expected an instance of type CustomJS. Please suggest if there is a fix/workaround for the above-mentioned error.

Also, suggest if there is an easy way to generate word clouds using bokeh?
