the error:
TypeError: Cannot read properties of undefined (reading 'add') at ListComponent.ngOnInit (index.js:11229:28) ...says what's wrong. Just go toListComponentto itsngOnInitmethod and check whe you useadd(method/property) and why its "owner" isundefined. After upgrading some flow or naming can change and cause such a problem.
