Hello

I'm trying to use AIP to import the entire site into a new server. I run the following command:
JAVA_OPTS="-Xmx4096m -Dfile.encoding=UTF-8" ./dspace packager -r -a -f -t AIP -e ad...@email.com -i 123456789/0 -o skipIfParentMissing=true /opt/dspace_aip_backup/sitewide-aip.zip

after some time i get this error:
The 'language.null' element has not been defined in this DSpace instance.

I took a look at the dspace.log and it doesn't have anything that references the error, just informational entries about the import but no ERRORs

Your help is appreciated

Hello,
This type of error when moving items from one DSpace instance to another usually means there are metadata fields in the original repository that don't exist in the new repository. I would check the Metadata Registry on both DSpace instances to make sure that the one you're trying to import into has all of the required metadata fields. That said, I don't think I've ever encountered "language.null", so I would also check the language metadata to make sure there are no issues with it.
