PythonSelenium隨機找不到元素

我的腳本對串列中的每輛車都做同樣的事情，但在隨機段落

vec = WebDriverWait(driver, 60).until(
                        expected_conditions.visibility_of_element_located((
                            'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')

找不到元素，我收到此錯誤：

我已經嘗試過類似的條件presence_of_element_located- 同樣的錯誤。這是完全隨機的。有任何想法嗎？

編輯：這是整個回圈：

for line in lines:
    if line[3] == '.':
        license_plate = line[23:33]
        name = line[38:52]
        vin = line[88:105]
        if '-' in license_plate and 'VSSZZZ' in vin:
            driver.switch_to.frame(driver.find_element('id', 'mainFs'))

            entry_license_plate = driver.find_element('id', 'elp.searchVehicle.input.licensePlate')
            entry_license_plate.send_keys(license_plate)

            driver.find_element('id', 'vaws.vehsearch.btn.search').click()

            vec = WebDriverWait(driver, 60).until(
                expected_conditions.visibility_of_element_located((
                    'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')

            WebDriverWait(driver, 60).until(
                expected_conditions.visibility_of_element_located(('id', 'vaws.sys.recall')))

            try:
                recall = driver.find_element('id', 'recall.info.state').get_attribute('src')
            except NoSuchElementException:
                recall = driver.find_element('id', 'recall.info.warning').get_attribute('src')

            if 'dummy.gif' in recall or 'info.gif' in recall:
                recall = 'Nein'
            elif 'warning.gif' in recall:
                recall = 'Ja'

            final_list  = f'{name} | {license_plate} | {vin} | Motor-Kennbuchstabe: {vec} ' \
                          f'| Feldma?nahme: {recall}\n'

            print('done')

            driver.switch_to.default_content()

            WebDriverWait(driver, 60).until(
                expected_conditions.visibility_of_element_located(('id', 'toolbar.button.new.job'))).click()

該頁面是我們公司的內部站點，所以我不允許顯示它。

uj5u.com熱心網友回復：

這只是意味著 60 秒超時結束而沒有觀察until方法中的內容。

嘗試將其放入 try 中：

try:
    vec = WebDriverWait(driver, 60).until(
                        expected_conditions.visibility_of_element_located((
                            'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')
except:
    print("Timeout")

或者，再試一次，直到我們沒有錯誤：

while True:
    try:
        vec = WebDriverWait(driver, 60).until(
                        expected_conditions.visibility_of_element_located((
                            'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')
        # break out of the loop if successful
        break
    except:
        # continue the loop if not successful
        continue
    print("Timeout")

uj5u.com熱心網友回復：

好的，我想我發現了問題：一開始我加載了默認組態檔

options.add_argument(f'--user-data-dir={os.getenv("LOCALAPPDATA")}\\Google\\Chrome\\User Data'

沒有它，我就沒有這些隨機錯誤。有誰知道為什么？
