Hello, I’m trying to change the demo to work on it but it keep crashing when I open the console windows, if I don’t open it it work perfectly fine.

Error: Uncaught TypeError: e is undefined (mobiscroll.react.min.js:2)
Then getting : Uncaught ReferenceError: process is not defined (blank line 49156 > injectedScript:2:13158)

Sorry in advance if the problem can be easily solved, I’m still learned and I’ve been stuck on it for a while now.

Hi @nauleau.vi

Welcome to the Mobiscroll Forum! I checked your code snippet, but I could not reproduce the error. Could you create a sample react app where this issue comes up? You can zip it without the node_modules folder and send it to me so I can investigate further.
