An error with Plotly renderers was showing in my charts (written some time ago, and using version 2.23.0 of pivot.js). I investigated your sample to see what I should do to correct the error and saw that the sample has the same error. I've solved the problem for myself by replacing the link to plotly-basic.min.js with an older version (1.33.1 - it works, however I didn't spend a lot of time checking to find the most recent 'non breaking' version). No more errors for me.
