Description
Hi,
I'm having trouble harvesting Clients with the Dataverse 5.11.1 version.
I get the message javax.ejb.EJBTransactionRolledbackException, Exception thrown from bean: java.lang.NullPointerException on the server log
Client configurations:
- Alias : UAB
- Server URL : https://ddd.uab.cat/oai2d
- OAI Set : datasets
- Metadata Format : oai_dc
- Archive type Generic OAI archive
Results :
SUCCESS; 0 harvested, 0 deleted, 78 failed.
Here is the log for the attempt :

Start by reviewing the attached harvest_UAB_2023-01-24T13-21-32.log and the reported Dataverse 5.11.1 harvesting configuration for the Generic OAI archive. Trace the javax.ejb.EJBTransactionRolledbackException and NullPointerException affecting the 78 failed records, then verify that harvesting the same OAI set completes without those failures.
