org.dspace.eperson.Group.getID()" because "groupChild" is null

[Job Diogenes Ribeiro Borges]

Hi all,

Using DSPACE 8.1

I did something like:

dspace packager -s -t AIP -e ad...@emai.com -p 123456789/999 aip-XXX.zip

But, get, the following error

Ingesting package located at aip-XX.zip

Hi Job,

That error appears to be saying that the AIP (zip file) you are ingesting is referencing a Group that doesn't exist in your system.  So, DSpace looks to be trying to ingest that AIP and either it is referencing a Group that doesn't exist, or maybe it tried to create a Group and failed to do so.

I'd recommend looking for other *prior* errors in your log file.  Or, more closely analyze the AIP to see if the groups in the "DSPACE-ROLES" section look correct based on your system.

It could also be that you should be using the "restore/replace mode" (-r) instead of the "submission mode" (-s), as those modes have different behaviors: https://wiki.lyrasis.org/display/DSDOC8x/AIP+Backup+and+Restore#AIPBackupandRestore-Thedifferencebetween%22Submit%22and%22Restore/Replace%22modes
