Package error when adding Builder to my Angular app

I can’t seem to get my Builder Section into my angular app. What am I doing wrong?

Builder content link

Builder public api key
fde02dd63056412fbdc80f5aa7e46996

Detailed steps to reproduce the bug

  1. Generated a clean new app with Angular 11 and the ng new command. I added routing and css.
  2. Followed the steps on the Builder GitHub of angular:
    - npm install @builder.io/angular
    - added the code to my module and in a component
  3. npm start

Code stack you are integrating Builder with
Angular 11

Reproducible code example
My errors:

  Try `npm i --save-dev @types/express` if it exists or add a new declaration (.d.ts) file containing `declare module 'express';`

Hi Daniel, we have a starter you can find here that uses Angular 11 and may help with your setup. If you’re still having issues could you please share your code with a Stackblitz that reproduces the error?
