当包含where查询参数时,firestoreconnect或firestore返回“未定义”

firebaseconnect hoc为“collections”返回未定义的值。但是,如果删除“where”参数,它将返回数据。

function mapStateToProps(state) {
  return {
    contestants: state.firestore.ordered['ContestantsList-contestants'],
    votes: state.firestore.ordered['ContestantsList-votes'],
    currentUserId: state.firebase.auth.uid,
  }
}

export default compose(
  firestoreConnect(ownProps => {
    // added this console log to verify that ownProps.contestId exists.
    console.log('ownProps', {...ownProps})
    return ([
      {
        collection: 'votes',
        where: [
          ['authorId', '==', ownProps.currentUserId],
          ['contestId', '==', ownProps.contestId],
        ],
        storeAs: 'ContestantsList-votes'
      },
      {
        collection: 'contestants',
        orderBy: ['createdAt', 'asc'],
        where: ['contestId', '==', ownProps.contestId],  // <---- If I remove this line, it works
        storeAs: 'ContestantsList-contestants',
      },
    ])
  }),
  connect(mapStateToProps),
)(ContestantsList);

在上面的代码中, votes prop是一个数据数组,正如预期的那样。这个 contestants 道具返回为未定义。我完全不知道为什么会这样。我希望这对一个有经验的firestore用户来说是显而易见的。我是刚到firebase和firestore的。
