Serverless Framework with AWS cognito generates CORS error

Question

I get this error message from the Angular frontend and I am not authorized to touch my lambda code:

`Access to fetch at \'https://testapicd.***.***.com/local         


        

Answer 1

This line in serverless.yml

arn: ${file(config.${self:provider.stage}.json):userpoolarn}

Should have been

arn: ${file(config.${opt:stage}.json):userpoolarn}
