Like the error says, your code is trying to do eval() and eval() is not allowed
See section 2 https://dev.twitch.tv/docs/extensions/guidelines-and-policies
Edit: was about to loop back and update this post with how to fix but @BehEh beat me
The problem you face is that if Alpine is doing it under the hood and you can’t change it to not use eval(), then you can’t use AlpineJS for Twitch Extensions.
