Vue with TypeScript encountering error: property does not exist on type

As I work on converting my JavaScript code to TypeScript, I have encountered an issue. My conversion attempt is shown below.

<script lang="ts">
 export default {
  data() {
    return {
      isShow: false as boolean
    }
  },
  methods: {
    openCalendar(): void {
      this.isShow = true;
    },
  }
}
</script>

Upon running the application, I receive an error in the console stating "Property isShow does not exist on type {open(): void;}". Where did I go wrong and how can I resolve this issue?

To enable type inference, you can try wrapping your options with Vue.extend({}):

<script lang="ts">
import Vue from 'vue'  
export default Vue.extend({
data() {
    return {
      isDisplayed: false as boolean
    }
  },
  methods: {
    showContent(): void {
      this.isDisplayed = true;
    },
  },
})
</script>
