When i tried to take screenshot of a webpage using selenium in python, i get error message selenium.common.exceptions.TimeoutException: Message: timeout: Timed out receiving message from renderer: 10.000.

Code:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
indi_url = 'http://www.google.com'
options = Options()
options.add_argument("disable-infobars")
options.add_argument("--start-maximized")
options.add_argument("--disable-popup-blocking")
options.add_argument("disable-popup-blocking")
options.add_argument("--disable")
driver = webdriver.Chrome(options=options)
driver.get(indi_url)
driver.implicitly_wait(30)
driver.save_screenshot("new.png")

Error message:

I'm using Chrome version 73, chromedriver version 73.

Note: code was working fine (ie.screenshot)in lower version of chrome and chrome driver.

Help me out in fixing this issue for new version of chrome driver.

Thanks in advance

As the error shows, your filename for screenshot does not match the template extensions .png

Here is an example how to make a screenshot.

Java:

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File(".\Screenshots\example_screenshot.png"));

Python:

driver.save_screenshot("screenshot.png")

This error message...

 UserWarning: name used for saved screenshot does not match file type. It should end with a .png extension
"type. It should end with a .png extension", UserWarning)

...implies that the Selenium-Python client encountered an issue while invoking get_screenshot_as_file() method.

get_screenshot_as_file()

get_screenshot_as_file() saves a screenshot of the current window to a PNG image file. Returns False if there is any IOError, else returns True. Use full paths in your filename.

• Args:
  
  
  • filename: The full path you wish to save your screenshot to. This should end with a .png extension.
  
  


• 
  

  Usage:

  
  
  

  driver.get_screenshot_as_file('/Screenshots/foo.png')
  

  
  


• 
  

  Defination:

  
  
  

  if not filename.lower().endswith('.png'):
   warnings.warn("name used for saved screenshot does not match file "
   "type. It should end with a `.png` extension", UserWarning)
  png = self.get_screenshot_as_png()
  try:
   with open(filename, 'wb') as f:
   f.write(png)
  except IOError:
   return False
  finally:
   del png
  return True
  

  
  

Analysis

As per the snapshot of the error stack trace:

You have used the command as:

driver.get_screenshot_as_file('new.jpeg')

The issues were:

• The filename didn't end with .png
  


• The desired full path of your filename wasn't provided.

Even if you desire to use save_screenshot() this method in-turn invokes get_screenshot_as_file(filename)

Solution

Create a directory within your project as Screenshots and provide the absolute path of the filename you desire for the screenshot while invoking either of the methods as follows:

• driver.get_screenshot_as_file("./Screenshots/YakeshrajM.png")


• driver.save_screenshot("./Screenshots/YakeshrajM.png")

Update

Currently GAed Chrome v73 have some issues and you may like to downgrade to Chrome v72. You can find a couple of relevant discussions in:

• Getting Timed out receiving message from renderer: 600.000 When we execute selenium scripts using Jenkins windows service mode


• Timed out receiving message from renderer: 10.000 while capturing screenshot using chromedriver and chrome through Jenkins on Windows
