AWS SAM Missing authentication token error on sample hello world app

Question

I'm setting up AWS SAM using VS Code on my Windows 10 development machine. When I create and start the sample hello world application I get Missing Authentication Token in the browser. See screenshot below.

Any suggestions on how to resolve would be appreciated.

Answer 1

You're simply calling a not-existing endpoint. There is a log line in your output which states how to access your function:

2019-07-01 21:56:50 Mounting HelloWorldFunction at http://127.0.0.1:3000/hello [GET]

So if you open http://127.0.0.1:3000/hello instead of http://127.0.0.1:3000/ you should get the output you're expecting.
