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

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)

Ah, any way to set the lambda up so it just gets triggered periodically (once/day) without it being started by invoking that path?
@KristofPlennings sure using your Schedule event is correct to do such things. with sam local you need to use generate-event then.. see my updated answer.
Thank you. I tried it and it returns a sample payload in the trend of: { "source": "aws.events" ... But my actual handleRequest doesn't seem to be executed. (handleRequest should create a dir to test it's doing something, but it's not being created). Thank you so much already. And noticed I should have checked: docs.aws.amazon.com/lambda/latest/dg/test-sam-cli.html better
you need to invoke it sam local invoke function-name -e event_file.json

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.

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 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.

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

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.
