Fails on IIFE code

[ajmeese7]

I have the following code from a CTF that I wanted to throw in here in case it would be able to break down some of the more obscure parts for me:

(()=>{"use strict";function t(e,r){const s=n();return(t=function(t,n){return s[t-=271]})(e,r)}function n(){const t=["88nTNxbi","674502feENOW","2032023SNqBbM","22BoFNoI","submit","520682ZYoYwM","8NCvxNF","351036juKBfo","607930DIkrQc","2UFTray","1335948eXCNaG","loginForm","/login","1304295IBrEeG"];return(n=function(){return t})()}function e(){const n=t,e=document.getElementById(n(274));e.action=n(275),e[n(281)]()}function r(){const t=["registerForm","6634359pNVFml","method","action","1UzWrqh","4251786JMOHtu","/testing/dev/api/v3/register","3379708uVuUSP","3eifQCL","POST","7797979AOoKKf","5986304ePFOpi","336692zuUMXy","submit","3688955HtwrSn"];return(r=function(){return t})()}function s(t,n){const e=r();return(s=function(t,n){return e[t-=199]})(t,n)}function o(){const t=s,n=document.getElementById(t(212));n[t(200)]=t(203),n[t(199)]=t(206),n[t(210)]()}function u(t,n){const e=c();return(u=function(t,n){return e[t-=194]})(t,n)}function c(){const t=["67370NVaJae","176Euyxzh","263842eCWWIF","48zypDZa","3946476BBFrMR","1017fiVBvr","395236JAWcZI","149765hIJPRp","143erIBdq","790092xcFjJE","10655Jtljli","3OkZlct"];return(c=function(){return t})()}function a(){const t=["249907cJcLKv","443991yBytqs","keyup","18638217IUPyOL","6gRcFCw","addEventListener","emailInput","name","1169515suZGLZ","24KlCwin","440075AUCbti","value","change","2091622XzcfjD","onload","innerHTML","Login","click","disabled","files","fileUploadInput","7387264hDtVhe","getElementById"];return(a=function(){return t})()}!function(n,e){const r=t,s=n();for(;;)try{if(369556==parseInt(r(282))/1*(parseInt(r(272))/2)+parseInt(r(278))/3*(-parseInt(r(283))/4)+parseInt(r(276))/5+-parseInt(r(273))/6+-parseInt(r(279))/7+parseInt(r(277))/8*(parseInt(r(284))/9)+parseInt(r(271))/10*(parseInt(r(280))/11))break;s.push(s.shift())}catch(t){s.push(s.shift())}}(n),function(t,n){const e=s,r=t();for(;;)try{if(669711==parseInt(e(201))/1*(parseInt(e(209))/2)+parseInt(e(205))/3*(parseInt(e(204))/4)+-parseInt(e(211))/5+-parseInt(e(202))/6+parseInt(e(207))/7+-parseInt(e(208))/8+parseInt(e(213))/9)break;r.push(r.shift())}catch(t){r.push(r.shift())}}(r),function(t,n){const e=u,r=t();for(;;)try{if(504549==parseInt(e(201))/1+parseInt(e(205))/2*(-parseInt(e(198))/3)+parseInt(e(203))/4+-parseInt(e(197))/5*(-parseInt(e(202))/6)+parseInt(e(194))/7*(-parseInt(e(200))/8)+-parseInt(e(204))/9*(-parseInt(e(199))/10)+parseInt(e(195))/11*(-parseInt(e(196))/12))break;r.push(r.shift())}catch(t){r.push(r.shift())}}(c);const i=p;function p(t,n){const e=a();return(p=function(t,n){return e[t-=241]})(t,n)}!function(t,n){const e=p,r=t();for(;;)try{if(872871==parseInt(e(249))/1+-parseInt(e(252))/2+-parseInt(e(263))/3+-parseInt(e(248))/4*(parseInt(e(247))/5)+-parseInt(e(243))/6*(-parseInt(e(262))/7)+parseInt(e(260))/8+parseInt(e(242))/9)break;r.push(r.shift())}catch(t){r.push(r.shift())}}(a),window[i(253)]=()=>{const t=i,n=document[t(261)](t(259)),r=document[t(261)]("fileUploadButton"),s=document[t(261)](t(245)),u=document[t(261)]("submitButton");s?(!s.value&&(u[t(257)]=!0),u[t(254)]===t(255)?u[t(244)](t(256),e):"Register"===u[t(254)]&&u[t(244)](t(256),o),s[t(244)](t(241),(()=>{const n=t,e=s[n(250)];-1==String(e).search(/^\s*[\w\-\+_]+(\.[\w\-\+_]+)*\@[\w\-\+_]+\.[\w\-\+_]+(\.[\w\-\+_]+)*\s*$/)?u[n(257)]=!0:u[n(257)]=!1}))):n&&(r[t(244)](t(256),(()=>{n[t(256)]()})),n[t(244)](t(251),(()=>{const e=t;r[e(254)]=n[e(258)][0][e(246)]})))}})();

But due to the IIFE nature of the code, I always get Error parsing Javascript Code when pressing the analyze button in the Docker image.
