在登录按钮后尝试在页面上单击按钮的是以下HTML

<div id="carrierDashboardControls">
      <button class="yms-button-primary" ng-click="refresh()">
         <t>Refresh</t>
      </button>
      <button class="yms-button-primary-alt ng-isolate-scope" ng-csv="fetchData()" lazy-load="true" 
  csv-header="getcsvHeader" filename="carrier-dashboard.csv" field-separator=",">CSV
      </button>
</div>

在此有2个按钮，我想单击一个与班级有关的按钮 “ yms-button-primary-alt ng-isolate-scope” 但是我得到以下错误

单击此按钮将下载CSV文件，但现在我收到错误消息“ selenium.common.exceptions.WebDriverException：消息：无法将数据转换为对象”

当前使用以下代码，请注意，由于业务性质，实际的网址无法共享（由于登录后重定向，我两次导航到该网址）

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
import re
import pandas as pd
import os


url = "THE URL"
username = 'username'
password = 'PASSWORD'

driver = webdriver.Firefox(executable_path=r'MYPATH/geckodriver.exe')
driver.implicitly_wait(100)
driver.get(url)

user_field = driver.find_element_by_id("ap_email")
pass_field = driver.find_element_by_id("ap_password")
sign_in = driver.find_element_by_id("signInSubmit")
user_field.send_keys(username)
pass_field.send_keys(password)
sign_in.click()
driver.implicitly_wait(100)
driver.get(url)
CSV_BUTTON = driver.find_element_by_class_name("yms-button-primary-alt ng-isolate-scope")
CSV_BUTTON.click()

作为补充，我想处理此后下载的文件，因为如果可能的话，我希望使用当前日期和时间自动重命名该文件？
