目前还不知如何复现,小程序正常使用情况下,有机率发生如下错误:

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.lengththis.patchIndexes undefined

请问要如何避免这个错误,谢谢

感谢反馈,是个比较复杂的内核错误。我们查一下。
