How to run locally with SAM #16

I have been experimenting with contract validation with OpenAPI and looking to try it against some lambda functions. However when I attempt to run locally with DOCKER_HOST=unix://$HOME/.docker/run/docker.sock sam local start-api --template template.yml I only get this output

Mounting /Users/alteredtech/Coding/xcode-apps/OpenAPI-Foundation as /var/task:ro,delegated, inside runtime container

Invalid lambda response received: Lambda response must be valid json
2024-12-05 09:54:21 127.0.0.1 - - [05/Dec/2024 09:54:21] "GET /pet/1 HTTP/1.1" 502 -

I was initially thinking it was this error with SAM but with that bootstrap error, it has me thinking its an issue with how I am deploying locally. I took at look at the swift lambda deployment but they do it slightly differently and do have some dockerfiles that add the bootstrap file to the docker image.

I can get this working using the local method in the docs LOCAL_LAMBDA_SERVER_ENABLED=true swift run but I am trying to mimic it being deployed so I can only use normal curl 127.0.0.1:3000/pet/1 without all the extra json in the Quote example.

I am using a slimmed down pet store openapi doc

openapi: 3.0.3
info:
  title: Swagger Petstore - OpenAPI 3.0
  description: |-
    This is a sample Pet Store Server based on the OpenAPI 3.0 specification.  You can find out more about
    Swagger at [https://swagger.io](https://swagger.io). In the third iteration of the pet store, we've switched to the design first approach!
    You can now help us improve the API whether it's by making changes to the definition itself or to the code.
    That way, with time, we can improve the API in general, and expose some of the new features in OAS3.

    Some useful links:
    - [The Pet Store repository](https://github.com/swagger-api/swagger-petstore)
    - [The source API definition for the Pet Store](https://github.com/swagger-api/swagger-petstore/blob/master/src/main/resources/openapi.yaml)

Oh I think I solved it. I had to update this line in the template

    CodeUri: .

to

    CodeUri: .aws-sam/build/PetStore

This might have been obvious to others but not I as I have not used SAM before.

hmmm so little issue I am discovering now. removed a path in the openapi doc. Now when I try to build with the solution I found I get this error.

sam build

Build Failed
Error: CustomMakeBuilder:MakeBuild - Makefile not found at /Users/alteredtech/Coding/xcode-apps/OpenAPI-Foundation/.aws-sam/build/PetStore/Makefile

The only way to get around this is by flip flopping between .aws-sam/build/PetStore and . for the CodeUri.
