Blocked by CORS policy: No 'Access-Control-Allow-Origin'

I am also having this CORS Policy error

for reference: I am working through

SERVERLESS 101
Task: Invoke the API Service using generated client SDK

I am unfamiliar with Javascript and am unsure where to look for my errors.

I imported the extra files

I am not sure whee to go next. I’d like to start by removing the CORS error.

When i look in the console at domain control, I believe it is set how it should be to not produce this error.
