EDITED: See my response below for my progress. I only need to find out how to refer to a function ARN from an openApi spec declared in the resources block.
I’m trialing the serverless.com
with AWS as the provider. I’d like to do a simple hello world app with API Gateway and Lambda, where I publish the API from an openapi spec.
I have seen in this forum post that I need to declare the spec as a resource in the serverless.yml file, but when doing so I get the following error when doing sls deploy
:
I think I have mostly correct, except that in the openapi spec file I don’t know how to correctly refer to the URI for the API I am creating (as I am creating the lambda function within the same serverless project). Is that the reason I am getting the error?
