I can build in my local machine without issues. First time this happen during an Angular update.

Minimal Reproduction

We have a custom script to trigger the build

"build-jenkins-pr-only": "node --max_old_space_size=8192 ./node_modules/@angular/cli/bin/ng build --configuration production --deploy-url /mco/js/angular4/",

Could this be related to #32127 ?
