Edit: Apps extend Construct, so you can use construct here. should've known that We don't have any ownership over the skill builder courses as far as I'm aware. So, I will suggest looking at our official documentation and guides instead 🙂 Let me know if you have any more questions or concerns I can help you with! |

Making that change gives me a slightly different error message: (And upgrading to CDK 2.21.1 doesn't make a difference here.) If I
which makes sense. Either way, there's definitely an error in the sample code in the video. But the video is the thing I need to complete in the AWS Certification process. Do you know where I should report the error to?

Also, having just tried, if I skip step 6, and just run with the default content of that TypeScript file (which also defines Default contents of import { Stack, StackProps } from 'aws-cdk-lib';
import { Construct } from 'constructs';
// import * as sqs from 'aws-cdk-lib/aws-sqs';
export class CdkPrimer2Stack extends Stack {
constructor(scope: Construct, id: string, props?: StackProps) {
super(scope, id, props);
// The code that defines your stack goes here
// example resource
// const queue = new sqs.Queue(this, 'CdkPrimer2Queue', {
// visibilityTimeout: cdk.Duration.seconds(300)
// });
}

I had the same problem, but this advice got me on the right track. The problem is that Amazon's CDK primer assumes we're using AWS CDK v1, but the files they provide contain a mix of both v1 and v2 dependencies (see here for more information). Perhaps this could be passed along to whomever has ownership of the primer. I fixed the problem in this way:
This allowed me to synthesize the app and move forward in the primer. My files ended up looking like this. 👇 package.json {
"name": "cdk_primer",
"version": "0.1.0",
"bin": {
"cdk_primer": "bin/cdk_primer.js"

Describe the bug
Following the instructions in the AWS CDK Demonstration code-along in AWS Skill Builder and the first time I'm asked to
cdk synthI get a compilation error, unlike the demonstration video.Expected Behavior
I expected the
cdk synthto execute correctly, outputting a non-error response that endslike on-screen.
Current Behavior
I get an error response, with the error occurring in one of the files I have not changed. (The instructions have only asked me to change the file
lib/cdk_primer-stack.tsso far; I have not editedbin/cdk-primer.ts.)Reproduction Steps
Following the instructions in the video, I have done the following:
sudo npm i -g aws-cdk/Users/owen.blacker/Projects/other/cdk-primer/)cdk init --language typescriptnpm i @aws-cdk/aws-ec2 @aws-cdk/aws-ecs @aws-cdk/aws-ecs-patternslib/cdk_primer-stack.tsto contain the TypeScript as belowcdk synthThe contents of
lib/cdk_primer-stack.tsonce edited are:Other than the video having an extra tab at the start of line 12 (
new ecs_patterns.ApplicationLoadBalancedFargateService(...)) and an extra linebreak after thatnewstatement, this is identical to the code on-screen.Possible Solution
No response
Additional Information/Context
No response
CDK CLI Version
2.21.0 (build 3f74a81)
Framework Version

Node.js Version
