You should specify formGroupName for nested controls   lt div class  panel panel-default  formGroupName  address  gt   lt    add this      lt div class  panel-heading  gt Contact Info lt  div gt    Plunker Example

I also had this error  and you helped me solve it  If formGroup or formGroupName are not written with the good case  then the name of the control is not found  Correct the case of formGroup or formGroupName and it is OK

In your HTML code   lt form  formGroup   userForm  gt       lt input type  text  class  form-control    value   item UserFirstName  formControlName  UserFirstName  gt       lt input type  text  class  form-control    value   item UserLastName  formControlName  UserLastName  gt   lt  form gt    In  your Typescript code  export class UserprofileComponent implements OnInit       userForm  FormGroup      constructor            this userForm   new FormGroup             UserFirstName  new FormControl              UserLastName  new FormControl                        This works perfectly  it does not give any error

I tried to generate a form dynamically because the amount of questions depend on an object and for me the error was fixed when I added ngDefaultControl to my mat-form-field        lt form  formGroup   questionsForm  gt           lt ng-container  ngFor  let question of questions  gt               lt mat-form-field  formControlName   question id  ngDefaultControl gt                   lt mat-label gt   question questionContent   lt  mat-label gt                   lt textarea matInput rows  3  required gt  lt  textarea gt               lt  mat-form-field gt           lt  ng-container gt           lt button mat-raised-button  click   sendFeedback    gt Submit all questions lt  button gt       lt  form gt    In sendFeedback   I get the value from my dynamic form by selecting the formgroup s value as such    sendFeedbackAsAgent   void       if  this questionsForm valid          console log this questionsForm value
