Production build fail after Angular upgrade document.documentElement.setAttribute is not a function

Question

I have upgraded my application to Angular 16 and upgrade went well and application is working as expected

But when I run the command for prod build

ng build --configuration=production

I got this error

Index html generation failed.
document.documentElement.setAttribute is not a function

I am not sure how to fix this as I don't have documentElement.setAttribute in my code

Setting optimization and buildOptimizer to false in angular.json does work but I know this is not right way to fix

any help or suggestion would be appreciated

Try remove node_modules and package-lock.json then run npm install
