AWS SAM - Template does not have any APIs connected to Lambda functions

So I'm trying to convert an existing spring boot application to an AWS lambda and using SAM.

I'm trying to use aws-sam-cli to try my lambda locally, however with my SAM setup I am getting: Template does not have any APIs connected to Lambda functions

When I do: sam local start-api

My template.yml:

AWSTemplateFormatVersion : '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: foo
Resources:
  MailFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: bar.LambdaHandler::handleRequest
      Runtime: java8
      CodeUri: target/foo-bar-1.0.jar
      Timeout: 300
      MemorySize: 1024
      Events:
        Timer:
          Type: Schedule
          Properties:
            Schedule: rate(1 day)

Any idea what I'm doing wrong? It looks correct as far as I can tell from https://blog.couchbase.com/aws-serverless-lambda-scheduled-events-tweets-couchbase/ + https://docs.aws.amazon.com/lambda/latest/dg/tutorial-scheduled-events-schedule-expressions.html

For Googlers:

  • Check whether you have an Event with Type: Api
  • ALSO check whether you have run sam build (very important)
  • Use the --debug flag so you will know what is going on

As of 2020/7/13, Type: HttpApi does not work with sam local start-api. See issue.

I am getting this error, but I have function that is working with the HttpApi, it appears that current version of sam does not support HttpApi.

CLI Version

SAM CLI, version 0.52.0

Example Function

FeedsFunction:
  Type: AWS::Serverless::Function
  Properties:
    CodeUri:
    Description: "Function that handles feeds"
    Events:
      Handler:
        Type: HttpApi
        Properties:
          ApiId: !Ref FeedsApi
          Path: /
          Method: get
    Handler: api
    MemorySize: 1024
    Runtime: go1.x
    Timeout: 5
    Tracing: Active

There is currently an open issue on GitHub for adding support: https://github.com/awslabs/aws-sam-cli/issues/1641

This error message also displays if you are trying to test a websocket API locally. Unfortunately, local testing of websockets is not currently supported - see https://github.com/awslabs/aws-sam-cli/issues/896.

I got this error when I had a whitespace error in my AWS::Serverless::Function definition, specifically Environment needed to be a child of Properties but was on the same level. Correcting the whitespace made this error disappear. Nodejs 10.15.

I ran into this error too even when I did have an Api event defined in my SAM template. The problem was that I had a previous template in my .aws-sam/build/ directory which didn't have the Api event defined (from a previous run of sam build). Cleaning out the build directory fixed it.

You didn't add any API Gateway event to your function. And start-api spawn a local API Gateway.

You need to add at least one Api event to your Events section.

Events:
  [...]
  Api:
    Type: Api
    Properties:
      Path: /myresource
      Method: get

If you just have a Schedule event, try to use generate-event to create such an event.

sam local generate-event schedule ...

and invoke function e.g. sam local invoke function-name -e event_file.json (see)
