Sankey diagram Error

[jitimon-sun]

Hello,

I tried to create Sankey following the instruction here https://github.com/googledatastudio/community-visualizations/tree/4cfd48a532f94fc8b2a1a1cb245de8f561cbd921/viz/sankey .
But I got this error after adding Visualizaition ID(my bucket name and already set as public)

I also tried using the deployed version. there was no error showing up, but the graph just not showing up until I moved or resized it, or sometimes it never shows up.

Did I miss something?
