使用AppleScript将Excel保存为PDF时出现参数错误

Question

我正在尝试使用AppleScript将Excel文件保存为PDF。它正常运行了2-3次，但突然开始 “错误” Microsoft Excel出现错误：参数错误。“数字-50”错误。

我不确定到底发生了什么变化。下面是我的代码：

on saveExcelAsPDF(documentPath, PDFPath)
set tFile to (POSIX path of documentPath) as POSIX file
tell application "Microsoft Excel"
    set isRun to running
    set wkbk1 to open workbook workbook file name tFile
    alias PDFPath -- This is necessary to any script for ‘Microsoft Office 2016’, this avoid errors with any “save ... ” command
    save workbook as wkbk1 filename PDFPath file format PDF file format with overwrite
    close wkbk1 saving no
    if not isRun then quit
end tell
end saveExcelAsPDF

saveExcelAsPDF("/Users/xyz/Documents/Excel/Book1.xlsx", "/Users/xyz/Documents/Excel/Book2.pdf")

error "Microsoft Excel got an error: Parameter error." number -50
