Jest encountered an unexpected token with react + konva and/or react-konva

See original GitHub issue

I’m getting the same error as posted on StackOverflow:

https://stackoverflow.com/questions/67919198/jest-encountered-an-unexpected-token-with-react-konva-and-or-react-konva

I’ve also tried the comment in the suggestion yarn add konva canvas to no effect.

This seems to be prevneting us from upgrading

Faced the same issue with Jest, react-testing-library. So I have started my investigation. I am going to update you here with my findings.

It seems that it’s some kind of issue with transpiling ESM to CommonJS.
