I am setting up the simplest community visualization. It only draws a blue rectangular on the canvas. However, as I upload my code to google cloud bucket and add the visualization to my Google Data Studio, it does not show anything.

Here is my code: https://storage.googleapis.com/gistic_default/myViz/myViz.js

The error shown in browser is: https://datastudio.googleusercontent.com/getThirdPartyScript?vizId=gs%3A%2F%2Fgistic_default%2FmyViz%C2%A0barChart&path=gs%3A%2F%2Fgistic_default%2FmyViz%2FmyViz.js&cacheBuster=1641850894876 net::ERR_ABORTED 500 which looks like GDS can not find the script.
