Question

我在这个应用程序中有多个函数返回promises，并且都用Flow类型注释。然而，有2个给我流动错误（它们确实有效），我似乎无法破译。任何见解将不胜感激！

const posts = await getPostRoutes({ brand, reusables, acf, wp })

声明

export async function getPostRoutes (
  { brand, reusables, acf, wp } :
  { brand: PropsBrand, reusables: Object, acf: string, wp: string },

) : Promise<Array<{
  path: string,
  component: string,
  getProps: Function,
}>> {
  const { data: posts_index } = await axios.get(`${acf}/options/posts_index`)
  const { data: posts } = await axios.get(`${wp}/posts?_embed`)

  return [{
    path: `${posts_index.acf.posts_index_blog_slug}`,
    component: 'src/containers/Posts',
    getProps: () => ({
      brand,
      title: posts_index.acf.posts_index_blog_title,
      subtitle: posts_index.acf.posts_index_blog_subtitle,
      reusables: {
        contact_columns: reusables['3_columns_contact_block_contact_columns'],
      },
    }),
    children: posts.map(post => ({
      path: `/${post.slug}`,
      component: 'src/containers/Posts/Post',
      getProps: () => ({
        ...cleanWPJson(post),
        brand,
        reusables: {
          ball_rolling_cta: {
            image: reusables.ball_rolling_cta_background_image,
            label: reusables.ball_rolling_cta_label,
            link: reusables.ball_rolling_cta_link,
          },
        },
      }),
    })),
  }]
}

流量错误

const recentPortfolioPieces = await getRecentPortfolioPieces({ wp, count: 3 })

声明

export async function getRecentPortfolioPieces (
  { wp, count } : { wp: string, count: number},

) : Promise<Array<{
  title: string,
  id: number,
  categories: Array<Object>,
  slug: string,
  thumbnail: {
    alt: string,
    url: string,
  },
}>> {
  const { data: recentPortfolioPieces } = await axios.get(`${wp}/portfolio?per_page=${count}`)
  return recentPortfolioPieces.map(piece => {
    return {
      title: piece.title.rendered,
      id: piece.id,
      categories: piece.pure_taxonomies.portfolio_cat,
      slug: '',
      thumbnail: {
        alt: '',
        url: '',
      },
    }
  })
}

流量错误

[flow] Promise (This type is incompatible with the expected param type of union: type application of class `Promise` | type parameter `T` of await Member 1: type application of class `Promise` Error: object literal This type is incompatible with the expected param type of object type Member 2: type parameter `T` of await Error: object literal This type is incompatible with the expected param type of object type)

我确信这与Flow如何理解我在这里缺少的承诺有关。再次，任何见解或帮助将不胜感激。
