Chat not working - step 25

[devpato]

I'm doing the zombie github tutorial and I'm on step 25. https://github.com/awslabs/aws-lambda-zombie-workshop. When I login and write a message i click "Enter" my message remains there, and the text field gets disabled and it doesn't get posted into the main square. Then if I click stop chatting and press again start chatting the textfield is still disabled, even if I logged out and log back in. Same happens if a create more accounts Do you experience this too? if yes how did you solve it?

I am still receiving this message as well. I worked around this by setting the Authorization mechanism to "None" instead of "AWS_IAM" for all GETs and POSTs. I'm still digging around the code trying to figure out where this needs to be fixed.
