从Access VBA覆盖电子表格时，运行时错误424

我试图使用Access VBA用Access查询的输出覆盖excel工作表。我在这里从这篇文章中获取并修改了一些很棒的Access VBA代码。任务完成了，但是最后我遇到了运行时错误：

运行时错误“ 424”：必需对象

修改后的代码如下。有什么想法为什么会这样？

Option Compare Database
Option Explicit

Private Const strFilePath As String = "C:\Users\MyPC\Desktop\Test Tracker\APS_Timeline_Status.xlsm"
Private Const strTQName As String = "q_APS_Timeline_Status_For_Export"
Private Const strSheetName As String = "TimeLine_Status"

Sub Update_timeline_tracker()

    SendTQ2XLWbSheet(strTQName, strSheetName, strFilePath).Run

End Sub


Public Function SendTQ2XLWbSheet(strTQName As String, strSheetName As String, strFilePath As String)

' strTQName is the name of the table or query you want to send to Excel
' strSheetName is the name of the sheet you want to send it to
' strFilePath is the name and path of the file you want to send this data into.

    Dim rst As DAO.Recordset
    Dim ApXL As Object
    Dim xlWBk As Object
    Dim xlWSh As Object
    Dim fld As DAO.Field
    Dim strPath As String
    On Error GoTo err_handler
 DoCmd.SetWarnings False

    strPath = strFilePath

    Set rst = CurrentDb.OpenRecordset(strTQName)

    Set ApXL = CreateObject("Excel.Application")

    Set xlWBk = ApXL.Workbooks.Open(strPath)
    Debug.Print strPath

    ApXL.Visible = True

    Set xlWSh = xlWBk.Worksheets(strSheetName)

    ApXL.DisplayAlerts = False

    xlWSh.Activate

    xlWSh.Range("A1").Select

    For Each fld In rst.Fields
        ApXL.ActiveCell = fld.Name
        ApXL.ActiveCell.Offset(0, 1).Select
    Next

    rst.MoveFirst

    xlWSh.Range("A2").CopyFromRecordset rst

    ' selects the first cell to unselect all cells
    xlWSh.Range("A1").Select

    rst.Close
    xlWBk.SaveAs FileName:="C:\Users\MyPC\Desktop\Test Tracker\APS_Timeline_Status.xlsm"
    xlWBk.Close
    ApXL.Quit

    Set rst = Nothing
