我正在尝试使用 cfzip 压缩目录但没有成功。新创建的目录包含 PDF。编码：

<cfset tempDir  = getTempDirectory() />
<cfset userDirName = CreateUUID() />
<cfset userTempDir = #tempDir# & #userDirName# />

<cfloop query="data">
  Create PDFs...[cfdocument]
<cffile action="write" file="#userTempDir#\#name#.pdf" output="#pdf_output#" addnewline="no" nameconflict="makeunique" />
</cfloop>             

<cfzip action="zip" source="#userTempDir#" file="#tempDir#/testZIP.zip" recurse="yes" />

一切都执行得很好，但 cfzip。当 cfzip 行尝试执行以下错误时：

The page you were executing caused an internal server error
