com.automationanywhere.packaging exception Packaging Exception: Cannot proceed with packaging as one of the input file is missing

I am also facing same issue.

I am also receiving this same error message while trying to export a bot that has no dependencies.  This error message is received when packages and included and when they are not included in the export; this does not seem to be a factor (looking at the response from @Micah.Smith).  After looking at my code, I noticed that some of the recorder capture actions are missing the image preview.  I had copied the code from an existing bot.  I believe the issue with the missing preview images may have been introduced with the .28 release.  If you are able to recapture your images, it may be fine for you.
