Selenium驱动程序在运行以下脚本时引发错误

Question

Html代码：

<div class="leftpan-button leftpan-button-active" ui-sref="main.poList({status: 'Finalize'})" ui-sref-active="leftpan-button-active" title="" href="#/main/po/Finalize">Finalize <!-- ngIf: vm.statusCount.PendingCount --><span class="badge pull-right ng-scope" style="background-color: rgb(255, 106, 0);" ng-if="vm.statusCount.PendingCount"></span><!-- end ngIf: vm.statusCount.PendingCount --></div>

Status list :<div class="panel-body tagList"><div class="leftpan-button leftpan-button-active" ui-sref="main.poList({status: 'Finalize'})" ui-sref-active="leftpan-button-active" title="" href="#/main/po/Finalize">Finalize <!-- ngIf: vm.statusCount.PendingCount --><span class="badge pull-right ng-scope" style="background-color: rgb(255, 106, 0);" ng-if="vm.statusCount.PendingCount"></span><!-- end ngIf: vm.statusCount.PendingCount --></div><div class="leftpan-button" ui-sref="main.poList({status: 'Pending for Approval'})" ui-sref-active="leftpan-button-active" title="" href="#/main/po/Pending%20for%20Approval">Pending for approval <!-- ngIf: vm.statusCount.PendingCount --><span class="badge pull-right ng-binding ng-scope" style="background-color: rgb(255, 106, 0);" ng-if="vm.statusCount.PendingCount" ng-bind="vm.statusCount.PendingCount">11</span><!-- end ngIf: vm.statusCount.PendingCount --></div><div class="leftpan-button" ui-sref="main.poList({status: 'Draft'})" ui-sref-active="leftpan-button-active" title="" href="#/main/po/Draft">Upcoming <!-- ngIf: vm.statusCount.UpcomingCount --><span class="badge pull-right ng-binding ng-scope" style="background-color: rgb(255, 106, 0);" data-ng-if="vm.statusCount.UpcomingCount" ng-bind="vm.statusCount.UpcomingCount">10</span><!-- end ngIf: vm.statusCount.UpcomingCount --></div><div class="leftpan-button" ui-sref="main.poList({status: 'Approved'})" ui-sref-active="leftpan-button-active" title="" href="#/main/po/Approved">Approved <!-- ngIf: vm.statusCount.ApprovedCount --><span class="badge pull-right ng-binding ng-scope" style="background-color: rgb(255, 106, 0);" data-ng-if="vm.statusCount.ApprovedCount" ng-bind="vm.statusCount.ApprovedCount">38</span><!-- end ngIf: vm.statusCount.ApprovedCount --></div><div class="leftpan-button" ui-sref="main.poList({status: 'Rejected'})" ui-sref-active="leftpan-button-active" title="" href="#/main/po/Rejected">Rejected <!-- ngIf: vm.statusCount.RejectedCount --><span class="badge pull-right ng-binding ng-scope" style="background-color: rgb(255, 106, 0);" data-ng-if="vm.statusCount.RejectedCount" ng-bind="vm.statusCount.RejectedCount">9</span><!-- end ngIf: vm.statusCount.RejectedCount --></div></div>

 driver.findElement(By.xpath("//*[@id='statusList']/div/div[1]").click();

driver.findElement(By.cssSelector("#statusList > div > div.leftpan-button.leftpan-button-active")).click();

 driver.findElement(By.linkText("Finalize")).click();

WebDriverWait wait = new WebDriverWait(driver, 30);// 1 minute
            wait.until(ExpectedConditions.visibilityOfElementLocated (By.cssSelector("#statusList > div > div.leftpan-button.leftpan-button-active")));

尝试下面的代码：

WebDriverWait wait = new WebDriverWait(driver, 9);
WebElement el = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("div.leftpan-button.leftpan-button-active[href$='/main/po/Finalize']")));

driver.findElement(By.cssSelector("div.leftpan-button.leftpan-button-active[href$='/main/po/Finalize']")).click();

告诉我发生了什么。
