https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18189 --- Comment #6 from Nick Clemens <nick@bywatersolutions.com> --- Before this patch passing sort options to Elastic gives an error much like the one you mentioned. If you are getting this before and after the patch I would suspect it is an issue with modules/versions, and or outdated mappings. Using admin/searchengine/elasticsearch/mappings.pl?op=reset&i_know_what_i_am_doing=1 should get your mappings up to date, then delete and rebuild indexes, and you should be good I would also check versions against kohadevbox elastic setup: https://github.com/digibib/kohadevbox/blob/master/roles/kohadevbox/tasks/ela... -- You are receiving this mail because: You are watching all bug changes.
