“预期的对象，得到了承诺。” 承诺作为道具传递时出错

Question

我只是尝试将 Promise 作为 Prop 传递给期望 Promise 的子组件，但我有一个错误，表明预期的类型是 Object。

我的项目使用TypeScript、vue-property-decorator和vue-class-component。

我的代码如下所示：

<template>
  <child-component :listPromise="listAsPromise"/>
</template>

<script lang="ts">
import { Component, Vue, Prop, Inject } from 'vue-property-decorator'
import  { EditableReferentielModel } from '@/api/model/referentiel'
import ReferentielResource from '@/api/resources/referentiel'
import { AxiosResponseExt } from '@/api/resources/index'

export default class ParentComponent extends Vue {
  @Inject()
  referentielResource: ReferentielResource

  listAsPromise: Promise<EditableReferentielModel[] & AxiosResponseExt> = this.referentielResource.getStadeDeveloppement()
}

</script>

<script lang="ts">
import { Component, Vue, Prop, Inject } from 'vue-property-decorator'
import ReferentielResource from '@/api/resources/referentiel'
import { EditableReferentielModel } from '@/api/model/referentiel'
import { AxiosResponseExt } from '@/api/resources/index'

@Component
export default class ChildComponent extends Vue {
  @Inject()
  referentielResource: ReferentielResource

  @Prop({ default: null })
  value: EditableReferentielModel | null
  @Prop({ default: null })
  listPromise: Promise<EditableReferentielModel[] & AxiosResponseExt>

  referentiel: EditableReferentielModel[] = []
  selected: EditableReferentielModel | null = this.value

  async mounted () {
    this.referentiel = await this.listPromise
  }
}
</script>

使用此代码，我仍然有此错误：[Vue warn]: Invalid prop: type check failed for prop "listPromise". Expected Object, got Promise.即使listPromise类型设置为any.

怎么了 ？
