But there are no errors when I build the application with ng build --prod what could be the reason for the error , as the same code is executing my other machine

appplication is also not maiking any API calls

this is where i am getting error in the core.js

Answer 2

The same problem with me.

Solution:

1. delete the project
2. clone project from your repo
3. npm install
4. open vscode and select > setting > Online services setting > settings sync > Edit in settings.json and change "angular.experimental-ivy": true to "angular.experimental-ivy": false

I have the same problem.

I tried to delete node_module and do npm install but it is not fixed.

Then, I finally remove @angular/material from package.json and reinstalled using npm install. It is solved.
