Hello!
I'm currently having this issue when concatenating my JS scripts. The original ones do not have this error, and this happens only with the "[HASH]-main.js" file. The error is "Uncaught ReferenceError: define is not defined ", and the problem is in the very end of the script:
,define("main",[],function(){})
is being added.
