#5 Fixing code every night - Why oneday my Facebook chatbot doesn't work, but it used to work before
In this video, I'm going to fix my 'tech shop' Messenger Bot. It used to work, but today, one of my friends tells me that the bot doesn't work anymore. After checking the logs of this chatbot, I figured out the problem: somehow Facebook updated their session, so I need to update the Facebook Page Access Token on the Developer page (the page manages the Facebook App).
I created a new Page Access Token, then updated the configuration on Heroku, and the problem is solved.
This video is made to answer the following message on my Facebook Fanpage (HaryPhamDev): I was trying to use the "Tech Shop Haryphamdev" chatbot but it doesn't work.
Thanks to: مهاب نورالدين البزنطي for letting me know the problem with my Tech Shop Bot : / techshopharyphamdev
The Facebook bot Logs:
message: Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons
