reactCustomScroll.js:289 Uncaught TypeError: Super expression must either be null or a function

[NaveenB]

the following error only on PROD deployment, on apache web server and also on azure app service deployment.

Works fine with local deployment with npm/ yarn start

What could be the issue?

Sorry, I don't have experience with those environments. Can you share a link or something similar where I can debug this?
Maybe instructions on how to reproduce?

[NaveenB]

Thanks for the response. Currently I don't have this code deployed anywhere. But I really like the animation part of scrollbar.

For me to understand, how I can setup the environment for you, to reproduce the issue, a question: do you have Microsoft Office 365 account? ( As the app has integration to MS OAuth)

[rommguy]

Yes, I have office 365 account

Having the same issue.

@mygurukool Maybe share the code + webpack config?

[rommguy]

@mygurukool, @martimarkov
Is this still relevant?

[EugeCos]

Yes, were getting this error on PROD after updating react-custom-scroll from version 4.1 to 4.2.2
Note that everything works fine on local environment.
