Describe the bug

I have been using version 2.115.0 of @aws-cdk/region-info and decided to update to the latest version, that being 2.200.1.

However, upon simply running my project I got this error immediately.

Error: Cannot find module 'aws-cdk-lib/core/lib/errors'

I made this simple script to show that it is not working at all.

package.json (or simply just run npm i @aws-cdk/region-info

{
  "name": "aws-testing",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "N/A",
  "description": "",
  "dependencies": {
    "@aws-cdk/region-info": "^2.200.1"
  }
}

Simple code:

const { Fact, FactName } = require("@aws-cdk/region-info");

const isValidRegion = (region) => {
    const myRegion = Fact.find(region, FactName.DOMAIN_SUFFIX);
    return myRegion !== undefined && myRegion !== null;
}

(() => {
    console.log(isValidRegion("us-west-2"));
})();

Using latest version results in the error I mentioned, if you use version 2.115.0 then this script works and returns true
