/Issues
If you run an ingest and you don't get any technical metadata, check to make sure the permissions on the fits folder and the fits.sh script are correct and the apache user can run the script.
Some images and audio files will cause problems during metadata extraction. These are not fatal errors, but appear to be formats the fits script can't understand. In these cases, you will get some error reporting in the technical metadata datastream that may help determine what happened.
IconIf you ingest an object but don't get any technical metadata, you may have forgotten to update the permissions on the fits.sh script. If that is not the case, make sure your configuration points to the correct file.
