• Add additional pre handlers that handle files to improve readability
  • getFiles is responsible checking the payload for any readable streams (i.e. files), files are assigned to request.pre.files
  • validateContentTypes reads the files from getFiles and checks their content type. This will also detect if the user did not upload anything for this field. It will attempt to find a previously uploaded file so the user can continue
• Refactored uploadService.handleUploadRequest into a pre handler, which calls uploadService
• Add additional logging for all steps
• Fix bug where we stopped showing "You have already provided this file"
  • This has now been changed to show the filename the user has uploaded, it now displays "You previously uploaded the file '..'"
  • The summary page can also display filenames if enabled. In the form json, add: "showFilenamesOnSummaryPage": true
