Cannot find module '@angular-builders/custom-webpack/package.json'

I'm trying to use @angular-builders/custom-webpack in an Angular9 project with Ivy enabled to use a custom webpack for server, but I got an error

An unhandled exception occurred: Cannot find module '@angular-builders/custom-webpack/package.json'
