I am trying to “undo” swapping to the new Angular es-build, as perhaps Ionic does not like it.

So, my angular.json now looks very similar to a new default Ionic/Angular project I created.

But now when I ng serve I get

[ng]     }
[ng]   ]
[ng] }
[ng] Node.js v20.15.1

I am guessing it is somthing in the architect tag, but looking in architect.js I cannot for the life of me work out what the above is talking about. I am not sure how to “debug” into it.

Would anyone have any ideas what is wrong with my angular.json?
