Encountering a TypeError stating that the "option is undefined" error has occurred

Unexpectedly, my dropdown menu that was functioning perfectly fine is now throwing an error. I've made several changes and none of them seem to resolve the issue. Could it be a data type mismatch or am I missing something crucial here?

Your insights on this matter would be greatly appreciated!

   <div class="col-sm-12 col-md-6 col-lg-4">
    <div class="form-group">
      <label>Deposit Holder</label>
      <v-select
              class="highlights"
              :options="select.offices"
              :on-change="selectOffice"
              :searchable="false"
              :clear-search-on-select="false"
              v-model="select.officeSelected"
      ></v-select>
    </div>
  </div>

 data() {
  return {
    now: new Date().toISOString(),
    loaded: false,
    document: {
      office_id: null,
    },
    select: {
      offices: [
        {
          'value': 1,
          'label': 'Nu World Title Kendall',
        },
        {
          'value': 2,
          'label': 'Nu World Title KW Kendall Office',
        },
        {
          'value': 3,
          'label': 'Nu World Title Miramar',
        },
        {
          'value': 4,
          'label': 'Nu World Title Davie',
        },
        {
          'value': 5,
          'label': 'Nu World Title Doral',
        },
        {
          'value': 6,
          'label': 'Nu World Title Miami Lakes',
        },
        {
          'value': 7,
          'label': 'Sanchez Vadillo Coral Gables',
        }
      ],
      officeSelected: '',
    }

methods: {
  selectOffice(option) {
    this.select.officeSelected = option;
    this.document.office_id = option.value;
  },

mounted() {
  this.selectOffice();
},

Answer №1

Within the mounted function, you're invoking this.selectOffice() without providing any arguments. The selectOffice method then attempts to access option.value, but because no parameter was passed, option is left as undefined.

I would have anticipated a generated stack trace along with the error message, which could have pinpointed the functions responsible for causing this issue.
