// Assuming you have a form group named 'myForm'
// You can access individual form controls using 'get' method

const formGroup = this.myForm; // Assuming 'this' refers to your component

Object.keys(formGroup.controls).forEach(field => {
  const control = formGroup.get(field);
  if (control && control.invalid) {
    console.log(`Field ${field} is invalid`);
  }
});


hint: use it inside NgOnInit, suncribe to the form valuechanges and console the Object.Keys...
