Exploring the depths of Angular8: Utilizing formControlName with complex nested

After dedicating numerous hours to tackle this issue, I finally came up with a solution for my formGroup setup:

 this.frameworkForm = this.formBuilder.group({
      id: [null],
      name: ['', Validators.required],
      active: [true],
      parsingRequired: [false],
      reviewRequired: [false],
      frameworkSortingType: {
        id: null,
        environmentalSortingType: '',
        socialSortingType: '',
        governanceSortingType: '',
      },
    });

While working on my template, I encountered a challenge in extracting value from environmentalSortingType:

     <div class="alphabetically">
                      <label class="control-label bold-label" for="reviewRequired">Alphabetically</label>
                      <div class="p-field-radiobutton">
                        <p-radioButton [name]="'environmental'" value="alphabetically"
                                       formControlName="frameworkSortingType.environmentalSortingType"
                        ></p-radioButton>

 <p-radioButton [name]="'environmental'" value="numerically"
                                   formControlName="frameworkSortingType.environmentalSortingType"
                    ></p-radioButton>
                      </div>

I struggled with the use of . in

formControlName="frameworkSortingType.environmentalSortingType"
. Any suggestions on how to overcome this hurdle? I've explored various approaches without achieving success:(

UPDATE

To address the issue, I adjusted my code by introducing a nested formGroup. However, I'm still encountering an error: Cannot find control with unspecified name attribute (

<div class="sorting" formGroupName="frameworkSortingType">
)

 ngOnInit() {
    this.frameworkForm = this.formBuilder.group({
      id: [null],
      name: ['', Validators.required],
      active: [true],
      parsingRequired: [false],
      reviewRequired: [false],
      frameworkSortingType: this.formBuilder.group( {
        id: null,
        environmentalSortingType: '',
        socialSortingType: '',
        governanceSortingType: '',
      }),
    });

Here is the updated section of my template:

  <div class="sorting" formGroupName="frameworkSortingType">
                <div class="alphabetically">
                  <label class="control-label bold-label" for="reviewRequired">Alphabetically</label>
                  <div class="p-field-radiobutton">
                    <p-radioButton [name]="'environmental'" value="alphabetically"
                                   formControlName="environmentalSortingType"
                    ></p-radioButton>
                  </div>
