Got everything on my AlexaBot to work but Robot will not move..Any Help

So I got everything on my Alexabot to work correctly and when I say “Alexa, Trigger Forward” applet shows that it is receiving the command, but the robot is not responding or moving. I am at the very last step and just stuck. Please Help. I think the issue might be in my flask server…
