[Koha] 500 Errors on search after update

After upgrading to the latest (22.05.02.000), I am getting 500 errors when a search should return a biblio entry. This happens on the OPAC and when I do a search under the cataloging section in the staff site. I am able to search for patrons with no apparent problem.(I did have quite a bit of trouble updating my database) I ran rebuild zebra and it made no difference. How do I detect what is causing this problem?
