Hello,
Unfortunately, we'd need more information about the exact error you are
seeing (preferably from the logs) to be able to help. Likely though,
either your OAI index may have gotten corrupted in some way, or there's a
specific Item (or a few items) that has not been indexed properly. You
could consider trying a full OAI reindex (which can take some time on a
large site) by running `./dspace oai import -c`.
I'd also recommend looking closer at your DSpace logs and pass along (to
this mailing list) the exact error stack. It looks like you are getting a
"NullPointerException" somewhere, but the location that is throwing that
error might be the most important piece of information. More info on
finding errors in the logs can be found here:

Good luck,
Tim
