Hey, Zach! First of all let me thank you for your amazing work. I studied your code and run it (the welcome comment bot). I'm running it on linux (pycharm) with everything set up. However, I'm always getting the error (Failed to comment on post). I really don't know why, I did everything. Sometimes it's working (the auhor's name appears in the console in the past authors array but if I visit my actual steemit profile and check the comment page, the comment was never posted). Can you help me out? It's driving me crazy. Thanks, looking forward to hearing your response. Cheers!
