Meteor JS无法调用非函数：undefined Error

Question

我的MeteorJS应用程序出现此特殊错误。最有趣的是，此错误仅在我的生产服务器上发生。检查localhost时，一切都是正确的，没有任何错误：

这里有错误：

setRecentHandsPagination = (data, sort) =>
  RecentHandsPagination.set
    filters: setFiltersForRecentHandsPagination(data)
    sort: setSortForRecentHandsPagination(sort)

setFiltersForRecentHandsPagination = (data) =>
  newFilters = new RecentHandsFilters(data).setFilters()

  Session.setPersistent 'recentHandsFilters', newFilters
  newFilters

setSortForRecentHandsPagination = (sort) =>
  newSort = if sort? then else {createdAt: 1}

  Session.setPersistent 'recentHandsSort', newSort
  newSort

AutoForm.hooks
  handsFilters:
    onSubmit: (data) ->
      @event.preventDefault()

      emptyFilters = []
      for filterName in PokerFiltersNames
        unless data[filterName]?
          emptyFilters.push filterName
          $("#handsFilters [data-schema-key='#{filterName}'] input[type='checkbox']")
            .prop 'checked', true
          $("#handsFilters [data-schema-key='#{filterName}'] option[value='#{Pocademy.AddedDate.THIS_MONTH}']")
            .prop 'selected', true

      if emptyFilters.length > 0
        defaultFilters = RecentHandsFilters.defaultAttrs()

      for filterName in emptyFilters
        data[filterName] = defaultFilters[filterName]

      setRecentHandsPagination(data)

      $('#dropdown-recent-hands.open').removeClass('open')
      @done()

Template.recentHandsFilters.helpers
  handsFiltersDefaultDoc: ->
    defaultFilters = RecentHandsFilters.defaultAttrs()

    filters =
      pokerGames: defaultFilters.pokerGames
      pokerTypes: defaultFilters.pokerTypes
      pokerVariants: defaultFilters.pokerVariants
      pokerTables: defaultFilters.pokerTables
      pokerCreatedAt: defaultFilters.pokerCreatedAt

Template.recentHandsFilters.events
  'click #showAllHandsBtn': (e) ->
    e.stopPropagation()
    AutoForm.resetForm 'handsFilters'

    setRecentHandsPagination()

    $('#dropdown-recent-hands.open').removeClass('open')

  'click #addHand': (e) ->
    e.stopPropagation()
    AutoForm.resetForm 'handsFilters'

  'click .cancel-dropdown': (e) ->
    e.stopPropagation()
    $('#dropdown-recent-hands.open').removeClass('open')

Template.recentHandsFilters.onDestroyed ->
  RecentHandsPagination.unsubscribe()

Template.recentHandsFilters.onCreated ->
  setRecentHandsPagination()

现在我很难对这个错误出现的原因做出任何假设。说实话过去几个小时我试图解决这个错误而没有任何成功。

可能错误是由下面的代码部分引起的，但我还不知道哪个部分：

function getValue(ctrlId) {
   return document.getElementById(ctrlId).value;
}

function isValidNumber ( val ) { return !isNaN(+val); }

function update() {
   var newGravity = getValue( 'grav' );
   if (isValidNumber ( newGravity ) ) gravity = newGravity ;
   //... same for other values.
}
