No videos specifically, but some tips that I've learned over the years.
1) Double clicking on an error in the log will take you to the line of code or step in your keyword test that generated the error. Start there. Is there something wrong with that step? Is there a mapped object that needs to be updated?
2) Drop a break point before the problematic piece of code to pause the automation prior to the issue. Then, slowly step through the automation and make sure every step is completed as expected. Pay special attention to page loads/form loads/refreshes that occur and verify that you have code to handle such things
3) Add log entries at various points around the trouble area so that, when you are running the automation at speed, you can track what it's doing when and determine if there's something happening that is not easily observable
4) Lastly, sit and watch. Start the automation and watch it carefully. Pay attention to what is being done where and the other effects on screen. Are there dialogs coming up that are interfering that you're not expecting? Do appication redraws/refreshes occur when you're not expecting? Are controls enabled appropriately after you perform an action or is there a slight delay?
These are the things that I do when I troubleshoot stuff that is not "obvious".
