Cannot read property 'kind' of undefined after upgrade to "@angular-devkit/build-angular": "^0.1001.0",

🐞 Bug report

Command (mark with an x)

• build
• serve

Is this a regression?

Yes, the previous version in which this bug was not present was: Prev version: 0.1000.7 Current Version: ^0.1001.0

Description

I’m using angular CLI project with multiple projects. After I upgrade the package json with the latest >> “@angular-devkit/build-angular”: “^0.1001.0”, I start to get this error: ERROR in Cannot read property ‘kind’ of undefined

For this command:

ng build project-name --prod --aot --source-map --build-optimizer

When I downgrade to 0.1000.7 it back to work

🔬 Minimal Reproduction

@ofirrifo, without debugging it’s hard to understand and find the root cause of the problem, though typically removing the lock file and node_modules does solve a number of issues.

[alan-agius4]

Same cause as https://github.com/angular/angular-cli/issues/18615 where the presence of an outdate version @angular-builders/custom-webpack is causing issues during module hosting.

Kindly update @angular-builders/custom-webpack to the latest stable version.

npm i @angular-builders/custom-webpack@10 -D
rm -rf node_modules package-lock.json
npm i

/workspace/ng-issue $ npm run serve:app

> ng-issue@0.0.0 serve:app /workspace/ng-issue
> ng serve app-a --open --port=4400
