🐞 Bug report

Command

• serve

Is this a regression?

It seems so. It stopped working after updating cli from 11.0.7 to 11.1.1

Description

Build optimizer breaks serve (build will be broken most probably as well) after updating to latest version.

Setting this config values breaks app

"aot": true,
"buildOptimizer": true,
"optimization": true,

However, the following settings work fine

"aot": true,
"buildOptimizer": false,
"optimization": false,

🔬 Minimal Reproduction

PR with updated dependencies and broken prod build rfprod/nx-ng-starter#201

Configuration reference (this one is broken prod; however, if buildOptimizer and optimization are turned off it will work) https://github.com/rfprod/nx-ng-starter/blob/2ebd5e142861d194be981b8a51d159627fc4686f/angular.json#L146-L163

Command

ng serve client --configuration production
