Running local api for nested serverless application locally

I have a serverless SAM-based service that has multiple Application resource referencing local templates, but running the template locally (with sam local start-api) doesn’t seem to recognize the nested applications.

Is it possible to run all of the referenced Applications as a single service locally?

Thanks

Facing the same problem here, I’ll try to add more context to the problem.

My team has multiple template.yml each template represent an API that we use, see the graph bellow:

src/
│   ├── contracts/
│   │    └── functions...
│   │    └── template.yml
│   ├── simulations/
│   │    └── functions...
│   │    └── template.yml
|   └── template.yml

So contracts and simulations will have their own template.yml that will contain all lambdas declarations and events. Then on template.yml of src we declare this API’s as nested applications, like this:

Resources:
  APIDomainName:
    Type: "AWS::ApiGateway::DomainName"
    Properties:

  # # API: Contracts
  ContractsApp:
    Type: AWS::Serverless::Application
    Properties:
      Location: src/contracts/template.yaml
      Parameters:

  # # API: Simulations
  SimulationsApp:
    Type: AWS::Serverless::Application
    Properties:
      Location: src/simulations/template.yaml
      Parameters:

What we want is that when we start a local api with sam local start-api on src folder their nested applications will be started too with their API’s. Currently, an error is returned because we do not have any http event on this template.yml (this events are on the nested applications).

This will be an awesome feature to sam thanks for this CLI btw.

@gerhardberger Do you find any workaround for this?

Hi, we also would like to have a feature like that: right now, during development, we use to run local start-api over the single nested stacks, but it doesn’t scale a lot…
