Ошибка запроса Firestore: ошибка 9. Не выполнено предварительное условие

У меня проблемы с работой этой функции Firebase, за исключением эмулятора Firebase.

Вот сообщение об ошибке. Про индексы там ничего не говорится, но я все же подозреваю, что виноват неправильный индекс.

Вот о какой функции идет речь. Я оставляю комментарии в тех частях, где предпринимал попытки устранения неполадок.

const filterTimesheetWorklogs = (worklogs, uid) => {
  return worklogs.filter(worklog => worklog.project.timesheetApprovers.includes(uid))
}

const isSpawnAllApproved = async (virtualTimesheetId, uid) => {
  // All timesheets with the same virtualTimesheetId with uid as one of the approvers are approved
  const collectionGroup = admin.firestore().collectionGroup("timesheets")
  const query = collectionGroup
    .where("virtualTimesheetId", "= = ", virtualTimesheetId)

  const snap = await query.get()

  const authorizedDocs = snap.docs.filter(async doc => {
    // const projectRef = doc.ref.parent.parent
    // const projectSnap = await projectRef.get()
    // const projectData = projectSnap.data()

    const { projectId } = doc.data()
    const projectCollectionGroup = admin.firestore().collectionGroup("projects")
    const projectQuery = projectCollectionGroup.where("timesheetApprovers", "array-contains", uid)
    const projectSnap = await projectQuery.get()
    const projectData = projectSnap.docs
      .map(doc => ({ id: doc.id, ...doc.data() }))
      .find(project => project.id === projectId)
    
    return projectData.timesheetApprovers.includes(uid)
  })

  return authorizedDocs.every(doc => {
    const data = doc.data()
    return data.status === "approved"
  })
}

const getAuthorizedVirtualTimesheets = functions.https.onCall(async (data, context) => {
  const { filter: { start, end }, companyId } = data;
  const { uid, token: { roles = {} } } = context.auth

  if ([
    Object.keys(roles).includes(companyId),
    roles[companyId].includes("timesheet approver") || roles[companyId].includes("admin"),
  ].some(v => !v)) {
    throw new functions.https.HttpsError("permission-denied", "Unauthorized access.");
  }

  const collectionGroup = admin.firestore().collectionGroup("virtualTimesheets")
  const query = collectionGroup
    // I've tried removing these two `.where`'s, error persists
    .where("createdAt", "> = ", dayjs(start).startOf("day").toDate())
    .where("createdAt", "< = ", dayjs(end).endOf("day").toDate())
  
  const snap = await query.get()

  // I've tried removing this entire statement and just return
  const docs = await Promise.all(snap.docs
    .map(async doc => ({
      id: doc.id,
      ...doc.data(),
      worklogs: filterTimesheetWorklogs(doc.data().worklogs, uid),
      status: (await isSpawnAllApproved(doc.id, uid)) ? "approved" : null,
    })))
  return docs
})

Другие попытки устранения неполадок:

• Создал составной индекс, как описано ниже (не работает):
  • ID коллекции: virtualTimesheets
  • Поля:
    1. createdAt АСЦ
    2. createdAt ДЕСК
  • Область применения: группа сбора
• Удалим как предложения where, так и оператор Promise.all (ошибка исчезнет).
