slightly different error now though

I am also experiencing similar issues. Just so you know you're not flying solo on this one

trying to see if i could find the answer on googles 😛 but cant see anything in the AWS stuff herehttps://cdkworkshop.com/20-typescript/70-advanced-topics/100-construct-testing/1000-assertion-test.html

@Kristian Lake @Devin the assert library has been revamped v2. Change this:

import { ... } from "@aws-cdk/assert";

expect(stack).to(
  haveResource("AWS::DynamoDB::Table", {
    BillingMode: "PAY_PER_REQUEST",
  })
);

to:

import { Template } from "aws-cdk-lib/assertions";

const template = Template.fromStack(stack);
template.hasResource("AWS::DynamoDB::Table", {
  BillingMode: "PAY_PER_REQUEST",
});

Thanks Frank. Managed to fix it up with the link you gave
