When using `this.array.find` within methods or computed properties in Vue, it sometimes returns

Within a component, I am receiving an array called approvalOptions from getters that contains a certain value I need to find.

I have attempted the following methods:

  1. Using it within methods (read from ...mapGetters) as shown below
methods: {
    approvalDisplayName(value) {
      console.log(this.approvalOptions)
      return this.approvalOptions.find(it => it.key === value).displayName;
    },
  },
  1. Utilizing it in computed properties instead of methods (with code sample similar to above)
  2. Implementing it within methods and reading from data properties as demonstrated below
data() {
   return {
   approvalOptions: [...(objects with keys and values here)]
   }
 },
methods: {
   approvalDisplayName(value) {
     console.log(this.approvalOptions)
     return this.approvalOptions.find(it => it.key === value).displayName;
   },
 },

Despite attempting all three methods, I consistently encounter an error message in the console indicating that approvalOptions.find(...) does not exist. The console.log output also displays the array, leaving me confused about what exactly is happening.

Perhaps this solution will be of assistance to you

computed: {
    selectedOptions() {
      return [
        { id: 1, name: "Option A" },
        { id: 2, name: "Option B" }
      ];
    }
  },
  methods: {
    displaySelected(options, value) {
      return options.find((item) => item.id === value).name;
    }
  },
  created() {
    console.log(this.displaySelected(this.selectedOptions, 1));
  }
