Similar to what you learned in both Creating Commands and [Creating

Solution:

for those using next.js set your version on something different than es5 (i used es2016)

Set it to es2022. Es5 is JavaScript of 2013, es2016 is well of 2016. It's super super old Also integrating sapphire within nextjs is asking for problems sooner or later. Sapphire and discordjs are no designed to run within a full stack framework.
