我在执行时收到Typescript错误错误错误如下所示：

TypeError: Cannot read properties of undefined (reading 'forEach')

这就是代码：

this.totalCount = response.total_rows;
this.bookmark = response.bookmark;
if (isPaginationCall && this.approvedForms && this.approvedForms.length > 0) {
    paymentForms.forEach(x => this.approvedForms.push(x));
} else {
    this.approvedForms = paymentForms;
}
this.onShowRecordChange();
setTimeout(() => {
    this.spinner.hide("MONITORPAYMENT");
}, 0);
