Hi,

    I am trying to upload and get  multiple file information. below I've given my VM file content.

#set($uploadedresponseFiles=[])
#if ($core_v2_page.IsPost)
#set($contextId = $core_v2_page.GetFormValue('contextId'))

#set($UploadedFiles = $core_v2_uploadedFile.List($contextId))


#foreach ($fileinfo in $UploadedFiles)
$uploadedresponseFiles.add([$fileinfo.FileDataBase64, $fileinfo.Name, $fileinfo.Url])
#end
$uploadedresponseFiles
#end
#end

After i execute i am getting below as response.
