Issues while Debugging CDK Lambda with SAM #3101

Question

Hi,

I'm trying to debug a lambda function with an aws-sam debug config for VSCode. The lambda function is part of an AWS CDK deployment. The function is fairly simple, it just reads some data from a DynamoDB table:

import {
    DynamoDBClient,
    ScanCommand
} from "@aws-sdk/client-dynamodb";

const TABLE_NAME = process.env.TABLE_NAME;

export const handler = async (event) => {
    const dynamoDB = new DynamoDBClient();
    try {
        switch (event.requestContext.http.method.toUpperCase()) {
            case "GET":
                return listEntities(dynamoDB);
            default:
                return "Not supported operation";
        }
    } catch (e) {
        return e;
    }
}

const listEntities = async (dynamoDB) => {
    const command = new ScanCommand({
        TableName: TABLE_NAME
    });
    const result = await dynamoDB.send(command);
    return result.Items.map(e => fromDatabaseEntity(e));
}

const fromDatabaseEntity = (item) => {
    return {
        id: item?.id?.S,
        name: item?.name?.S
    };
}

After synthesizing the CDK (cdk synth) and executing the following command via SAM, I'm able to run the lambda locally (the lambda is exposed at the correct path and the data is fetched from the remote AWS DynamoDB table):

sam local start-api -t cdk.out/ApplicationStack.template.json --profile admin

However, if I try to debug the the lambda function with the following launch config, I got this:

{
    "configurations": [
        {
            "type": "aws-sam",
            "request": "direct-invoke",
            "name": "my-service:src/index.handler (nodejs16.x)",
            "invokeTarget": {
                "target": "code",
                "projectRoot": "${workspaceFolder}/apps/my-service",
                "lambdaHandler": "src/index.handler"
            },
            "lambda": {
                "runtime": "nodejs16.x",
                "payload": {
                    "json": {
                        "requestContext": {
                            "http": {
                                "method": "GET"
                            }
                        }
                    }
                },
                "environmentVariables": {
                    "TABLE_NAME": "my-demo"
                }
            },
            "sam": {
                "localArguments": [
                    "--profile",
                    "admin",
                    "--region",
                    "eu-central-1"
                ]
            }
        }
    ]
}

Note: I was forced to use sam.localArguments to provide the profile and the region, as for some reason when setting aws.credentials I got the following in the log Loading AWS credentials from session with profile 'None'.

Here is the log from the debug session:

Thank you for the thoughtful bug report!

  • I'm able to debug until line 26 (const result = await dynamoDB.send(command);), where the DynamoDB table is being queried.
  • After I press Step Over or Continue with breakpoint on the next line, the debug session suddenly stops and I don't get the results from the DynamoDB.

Hi @justinmk3

No, it seems that the process exits. Instead of performing a get query, I've tried to insert records in the DynamoDB table - the process exits and there are no records in the table. Also I've tried to console.log() or writeFileSync() after the call to the DynamoDB, but nothing happens.

All I get is the following message in the Debug Console:

END RequestId: dd2ce95f-bc80-4153-aa8d-8ec01497b924
REPORT RequestId: dd2ce95f-bc80-4153-aa8d-8ec01497b924  Init Duration: 2.56 ms  Duration: 26659.14 ms   Billed Duration: 26660 ms   Memory Size: 128 MB Max Memory Used: 128 MB

I've also tried to List Buckets from S3, but it's the same behaviour.

I don't have installed WebStorm, could give it a try.
