python win32com 运行word宏传参问题

Question

win32com 模块传参报异常。
我的vba代码如下：

Sub 图片导入()
'
' 图片导入 宏
'
'
    a = InputBox("同APP下打开的world文档名称？")
    b = InputBox("需要插入图片的位置？")
    
    Windows(a).Activate
    Selection.Find.ClearFormatting
    With Selection.Find
        .Text = b
        .Replacement.Text = ""
        .Forward = True
        .Wrap = wdFindContinue
        .Format = False
        .MatchCase = False
        .MatchWholeWord = False
        .MatchByte = True
        .MatchWildcards = False
        .MatchSoundsLike = False
        .MatchAllWordForms = False
    End With
    Selection.Find.Execute
    Selection.PasteExcelTable False, False, False
    Selection.Tables(1).Rows.Alignment = wdAlignRowCenter
    Selection.Tables(1).AutoFitBehavior (wdAutoFitContent)
    Selection.Tables(1).AutoFitBehavior (wdAutoFitContent)
End Sub

Sub 图片导入2(a, b)
'
' 图片导入 宏
'
'
   
    Windows(a).Activate
    Selection.Find.ClearFormatting
    With Selection.Find
        .Text = b
        .Replacement.Text = ""
        .Forward = True
        .Wrap = wdFindContinue
        .Format = False
        .MatchCase = False
        .MatchWholeWord = False
        .MatchByte = True
        .MatchWildcards = False
        .MatchSoundsLike = False
        .MatchAllWordForms = False
    End With
    Selection.Find.Execute
    Selection.PasteExcelTable False, False, False
    Selection.Tables(1).Rows.Alignment = wdAlignRowCenter
    Selection.Tables(1).AutoFitBehavior (wdAutoFitContent)
    Selection.Tables(1).AutoFitBehavior (wdAutoFitContent)
End Sub

在word文件中运行vba程序正常，但是在python中庸win32调用vba运行一直报错，但是调用其他不需要传参的vba可以正常运行。python代码如下：

docApp = win32com.client.DispatchEx('Word.Application')
    doc = docApp.Documents.Open(doc_path)
    vba_doc = docApp.Documents.Open(vba_path_world)
    for pic in pictures:
        print(pic)
        sheet.range(pic.split('-')[1]).api.Copy()
        docApp.Application.Run(f"{vba_path_world}!图片导入2",'a.docx',pic)  
        print('ok')

    doc.Save()
    vba_doc.Save()
    docApp.Quit()

    vba_xlsm_wb.close()

错误代码如下：
Traceback (most recent call last):
File "E:\个人\python\python_excel\新建文件夹\Excel转换为world.py", line 176, in
docApp.Application.Run(f"{vba_path_world}!图片导入2",'T$$-c61') #,doc_save_name,pic
File "<COMObject >", line 8, in Run
File "C:\Users\Administrator\AppData\Local\Programs\Python\Python39\lib\site-packages\win32com\client\dynamic.py", line 314, in ApplyTypes
result = self.oleobj.InvokeTypes(*(dispid, LCID, wFlags, retType, argTypes) + args)
pywintypes.com_error: (-2147352567, '发生意外。', (0, None, None, None, 0, -2147352573), None)

Process finished with exit code 1

查了半天也没有找出问题，请大家指点，谢谢。
