@let records = _routeData().data;
@for (record of records; track $index; let last = $last) {
@let author = record.userInfo;
@let article = record.article;
@let statistic = record.articleStatistic;
<section class="article">
<div class="author">If insert an empty ng-container before @let, the error goes away
@let count = _routeData().count;
@let records = _routeData().data;
@for (record of records; track $index; let last = $last) {
