undefined 'this.patchIndexes.length'

时间：2019-05-03 来源：小程序工厂

    SDKVersion 1.9.0
    brand iPhone
    model iPhone 6s
    system iOS 11.2.1
    version 6.6.1


    目前还不知如何复现，微信小程序超过审核时间，微信小程序开发。微信小程序正常使用情况下，有机率发生如下错误:exparserScriptError value@https: undefined is not an object (evaluating 'this.patchIndexes.length')

    发生在内核程式库
    a = function() {
    function e(t, n) {
    r(this, e), this.oldTree = t, this.patches = n, this.patchIndexes = Object.keys(this.patches).map(function(e) {
    return Number(e)
    })
    }

    return o(e, [{
    key: "apply",
    value: function(e) {
    var t = this;
    if (0 === this.patchIndexes.length) return e;
    var n = (0, i.getDomIndex)(e, this.oldTree, this.patchIndexes);
    return this.patchIndexes.forEach(function(e) {
    var r = n[e];
    if (r) {
    t.patches[e].forEach(function(e) {
    e.apply(r)
    })
    }
    }), e
    }
    }]), e
    }();

    看似不明原因，this.patchIndexes.length 之 this.patchIndexes 是 undefined
    请问要如何避免这个错误，谢谢
