aws-serverless-java-container: The incoming event is not a valid request from Amazon API Gateway or an Application Load Balancer

Framework version: latest
Implementations: Spring Boot

Scenario

I’m trying to create two Spring Boot function. One supposed to call the other, I can call both from outside (Api Gateway), but if I try to do it directly with lambda invoke I get this: The incoming event is not a valid request from Amazon API Gateway or an Application Load Balancer either from code or from the lambda console. What am I missing?

Expected behavior

Works the same way with invoker as through api gateway.

Actual behavior

Only works with api gateway.

Steps to reproduce

The code is here: https://github.com/balihb/fifi

./gradlew :aws:buildFibZip :aws:buildFibtimerZip
cd aws
./deploy.sh

I’m getting the same error: The incoming event is not a valid request from Amazon API Gateway or an Application Load Balancer I have the following configuration:
  SomeEndpoint:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: SomeCodeUri
      Handler: LambdaHandler::handleRequest
        Warmup:
          Type: Schedule
          Properties:
            Schedule: cron(0/5 8-17 ? * MON-FRI *)
I think a http method is expected on the request judging by what I see here:
if (request.getHttpMethod() == null || request.getHttpMethod().equals("") || request.getRequestContext() == null) {
            throw new InvalidRequestEventException(INVALID_REQUEST_ERROR);
        }
Do we have a sample handler class for this error? This is happening because the warmup plugin sends an event but it is not a gateway event. We should have a condition to return directly if the request is coming from warmup plugin.

It’s been a while since I’ve played with this and I don’t have the sample to provide it. Meanwhile we’ve dropped the warmup part.

I am trying to deploy the spring boot project generated by Maven archetype for Spring Boot 2.x on AWS lambda and calling its /ping endpoint with the help of AWS API gateway but I am getting the same error reported here i.e The incoming event is not a valid request from Amazon API Gateway or an Application Load Balancer

Here is my code:

https://my-lambda-code-bucket.s3.us-east-2.amazonaws.com/my-service-1.0-SNAPSHOT-lambda-package.zip

Here is my api endpoint: https://gpvvq6g3i1.execute-api.us-east-2.amazonaws.com/Prod/ping

Hey @balihb - the framework expects an event that is shaped like an API Gateway or ALB proxy event. That doesn’t mean that the call must come from API Gateway or ALB, just that the event should have the same model. If you wanted to, you could use the AwsProxyRequest object from the model package to generate the event.

If these two Lambda functions are meant to be separate services - meaning they have different scaling factors and will eventually be managed by separate teams - I’d recommend putting an actual API in-between them.
