リモートブラウザとの通信でエラーが発生した可能性があります。

Question

この質問は何度も尋ねられていますが、それらをチェックしても解決できませんでした。アウトなぜそれがコードの行の下に実行.After発生している

driver.get(first_url) 
    #here i open forst url the perform some operation  
    main_window =driver.current_window_handle 
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + "t") 
    #above line opens a new tab 
    # Put focus on current window which will, in fact, put focus on the current visible tab 
    main_window_new =driver.current_window_handle 
    driver.switch_to_window(main_window_new) 
    time.sleep(1) 
    driver.get(second_url) 
    #opening new tab in the existing browser 
    time.sleep(2) 
    json_str=driver.find_element_by_tag_name('body').text 
    time.sleep(1) 
    print json 
    # Close current tab 
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w') 

    # Put focus on current window which will be the window opener 
    driver.switch_to_window(main_window)

何か助けていただければ幸いです。

タブが1つだけ開いている場合は、次の行でブラウザが閉じられるため、

# remove that line and run your code. You will not see this error again. 
driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')
