I am trying to use AppSync for my project. Although I have handled everything according to the design documentation, I keep encountering the error:
{"payload":{"errors":[{"message":"Required headers are missing.","errorCode":400}]},"type":"connection_error"}
every time I create a subscription to listen. Is this a bug, or am I missing something? Please help me resolve this issue.
