log type 'client' not found in pytest selenium

Question

 logs = selenium.driver.get_log('client')
 selenium.common.exceptions.WebDriverException: Message: unknown error: log type 'client' not found
  (Session info: headless chrome=87.0.4280.88)
  (Driver info: chromedriver=2.38.552518 (183d19265345f54ce39cbb94cf81ba5f15905011),platform=Mac OS X 10.13.6 x86_64)

I have set the desired capabilities:

dc = DesiredCapabilities.CHROME
dc['goog:loggingPrefs'] = {'browser': 'ALL',
                           'driver': 'ALL',
                           'client': 'ALL',
                           'server': 'ALL',
                           'performance': 'ALL'}

Please note logs = selenium.driver.get_log('browser') works fine

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: log type 'client' not found
  (Session info: headless chrome=87.0.4280.88)
  (Driver info: chromedriver=2.38.552518 (183d19265345f54ce39cbb94cf81ba5f15905011),platform=Mac OS X 10.13.6 x86_64)

...implies that though you are using chrome=87.0.4280.88 but your chromedriver version is 2.38.552518 which old and ancient.

Solution

Ensure that:

Selenium is upgraded to current released Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v87.0 level.
Chrome is updated to current Chrome Version 87.0 level. (as per ChromeDriver v87.0 release notes).
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
