支付完成后捐赠记录间歇性异常：Undefined property: stdClass::$donate_amount

支付完成且金额成功扣除后，系统本应跳转回站点并记录捐赠记录，但该问题为间歇性触发，并非每次都会出现。同时触发报错：
Undefined property: stdClass::$donate_amount

相关代码片段如下：

<div class="row justify-content-center">
  <div class="col-lg-10 mt-3">
    <div class="row">
      <div class="col-12 grid-margin stretch-card">

          <div class="card">
            <div class="card-body">
              <div class="wrapper d-block d-sm-flex align-items-center justify-content-between">
                <h4 class="card-title mb-0">{{ __('translation.Invioce Details') }}</h4>
                <ul class="nav nav-tabs tab-solid tab-solid-primary mb-0" id="myTab" role="tablist">
                  <li class="nav-item">

                      id="info-tab"
                      data-toggle="tab"
                      href="#info"

                      aria-controls="info"

                  <li class="nav-item">

                </ul>
              </div>
