未定义的（在承诺中）typeError：无法读取未定义的属性（Reading＆＃x27; OnClick＆＃x27; - JavaScript

Question

谁知道错误是什么，我不明白为什么会引发错误，我尝试进入控制台，而代码有效...

var array_Hilos_FOROMAESTRO = [];
var array_cantidad_FOROS = [];

async function fncCalcularEntradas() {
    var array_Hilos_FOROMAESTRO = [];
    var array_cantidad_FOROS = [];
    //consulta foros 
    var consulta = document.evaluate(xpath_consulta_FOROS, document, null, XPathResult.ANY_TYPE, null);
    var consultaIter = consulta.iterateNext();
    while(consultaIter){
        array_cantidad_FOROS.push(consultaIter)
        consultaIter = consulta.iterateNext();
    }
    //consulta hilos
    var hilos = document.evaluate(xpath_temas_FOROMAESTRO, document, null, XPathResult.ANY_TYPE, null);
    var hilosIter = hilos.iterateNext();
    while(hilosIter){
        array_Hilos_FOROMAESTRO.push(hilosIter);
        hilosIter = hilos.iterateNext();
    }
    for (let index = 0; index <= array_Hilos_FOROMAESTRO.length; index++) {
        array_Hilos_FOROMAESTRO[index].onclick()
        fncCopiaForo();
        for(let i = 0; i < array_cantidad_FOROS.length ; i++){
          if(array_cantidad_FOROS[i].classname =='submenu_link active'){
              array_cantidad_FOROS[i].onlick();
          }  
        }   
    }
}
