Unable to locate control with undefined name attribute in Angular version 14

I'm encountering the following issue.

https://i.sstatic.net/fV1D1.png

When I click on the area indicated by the BLUE ARROW in the image above, it leads to the of of ngFor loop in my html template.

     <div class="w-[60%]">
       <select
        name="duration"
        id=""
        class="text-[1rem] leading-6 py-2 px-8 border border-[#BCBCBC] w-[27.875rem] rounded-md focus:outline-none focus:border-primary"
        [formControl]="demoLength"
        required
      >
        <option
          [value]="timing.value"
          *ngFor="let timing of staticDurationArray"
          selected="{{ timing.selected }}"
        >
          {{ timing.time }}
        </option>
      </select>
    </div>

Furthermore, the staticDurationArray in the code above is an array containing static data in the TS file

staticDurationArray = [
    {
      time: '15 min',
      value: 15,
      selected: '',
    },
    {
      time: '30 min',
      value: 30,
      selected: '',
    },
    {
      time: '45 min',
      value: 45,
      selected: '',
    },
    {
      time: '1 hr',
      value: 60,
      selected: '',
    },
]

After adding an *ngIf condition to my code, I successfully resolved the issue I was facing.

<div class="w-[60%]">
              <select
                *ngIf="demoLength"
                [formControl]="demoLength"
                name="duration"
                id=""
                class="text-[1rem] leading-6 py-2 px-8 border border-[#BCBCBC] w-[27.875rem] rounded-md focus:outline-none focus:border-primary"
                required
              >
                <option
                  [value]="timing.value"
                  *ngFor="let timing of staticDurationArray"
                  selected="{{ timing.selected }}"
                >
                  {{ timing.time }}
                </option>
              </select>
            </div>
