TypeError: Super expression must either be null or a function

Hey everyone

I have a react app written in TS and used gif.js for generating some GIF images.
It compiles and works well, but when I run the unit tests using the jest command, it raises this error:

TypeError: Super expression must either be null or a function

Any advice?
