ScienceCloud: Project Data Registrations Improved Error Messages

Previously when submitting a file for registration in Project Data, a user could receive a vague error message such as "Internal Error - An internal error occurred. Please contact ScienceCloud support." These error messages have been improved to indicate to the user what the issue might be in order for them to resolve it on their own without the need for support intervention. This was released with the ScienceCloud 2021 SP4 release.
