Question

Hi, I have a test project with a lambda, based off: ( https://github.com/aws-samples/aws-saas-factory-ref-solution-serverless-saas ) I am able to invoke with sam local from the cli and it works perfectly, but vsCode debug fails, I am fairly sure it's a vsCode configuration issue.

note: I tried both GetOrderLambdaHandle and getOrder in the lambdaHandler field of the configuration, same error.

Thank You!

Details:
Cli Invoke ( Works ):

sam local invoke GetOrderLambdaHandle -e ./test/events/basicEvent.json -t ./cdk.out/OrderServiceStack.template.json

Basic Error:
Runtime.MalformedHandlerName","errorMessage":"Bad handler","stack":["Runtime.MalformedHandlerName: Bad handler"," at _splitHandlerString (file:///var/runtime/index.mjs:990:15)

Error and Supporting Details :

Debugger attached.

One Lambda:

import { Handler } from 'aws-cdk-lib/aws-lambda';
import { Logger } from "../common/logger";
import { OrderServiceDal } from "./order_service_dal"

const log = new Logger()
export const getOrder: Handler = async(event: any, context: any): Promise<any> => {
    console.log(event);
    const tenantId = event['requestContext']['authorizer']['tenantId'];
    log.logWithTenantContext(event, tenantId);
    log.info("Get Order Request");

    let params = event['pathParameters'];
    let key = params['id'];
    let order = await OrderServiceDal.get().getOrder(event, key);
    return order;
}

import { Construct } from 'constructs';
import path = require('path');
// import * as sqs from 'aws-cdk-lib/aws-sqs';

export class OrderServiceStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const getOrderLambda = new NodejsFunction(this, "GetOrderLambdaHandle", {
      runtime: Runtime.NODEJS_20_X,
      entry: path.join(__dirname, `/business_layer/order_service.ts`),
      handler: "getOrder"
    });
  }
