How to enable Debug logging for the Chromium Embedded Framework (CEF) Browser


Question / Problem: 

Debug logs are sometimes needed for robots using the Chromium Embedded Framework (CEF) browser to track down execution problems.

Answer / Solution: 

To enable debug logging for CEF follow the steps below:


  1. Navigate to the Kapow Installation folder
    by default, for versions 10.3 and earlier: C:\Program Files\Kapow <version>\
    for versions 10.4 and later: C:\Program Files\Kofax RPA <version>\
  2. go into \nativelib\hub\windows-x32\<id>\node_modules\cef
  3. open cef.cfg in a text editor (you will need to be able to save changes)
  4. add the following two lines at the end

    chrome:log-file = C:\Temp\debugCEF_10322.log
    chrome:log-severity = verbose

    Note: log-file can be different, but the folder has to already exist.
  5. Save cef.cfg
  6. Re-run the robot
