Only works when getModule() from vuex-module-decorators is in the code

[stefaanv]

The below code works fine, but when I remove the two getModule calls (which aren't supposed to be there according to the examples), I get the underneath error message.

I'm using Vue 3.

<script lang="ts">
import { Component, Vue, Watch } from 'vue-property-decorator'
import { getModule } from 'vuex-module-decorators'
import { namespace } from 'vuex-class'
import Counter from '@/store/module/Counter'
import PositiveCounter from '@/store/module/PositiveCounter'

const counterStore = namespace('Counter')
const posCounterStore = namespace('PositiveCounter')

@Component({})
export default class CounterComp extends Vue {
  // These two lines shouldn't be there according to the documentation
  counterModule = getModule(Counter, this.$store)
  posCounterModule = getModule(PositiveCounter, this.$store)

  @counterStore.Getter('formatted') counterValue!: number
  @counterStore.Action('decrement') decrementCounter!: () => void
  @counterStore.Action('increment') incrementCounter!: () => void

  @posCounterStore.Getter('formatted') posCounterValue!: number
  @posCounterStore.Action('decrement') decrementPosCounter!: () => void
  @posCounterStore.Action('increment') incrementPosCounter!: () => void
}
</script>

Error message when removing the `getModule()` calls
