I have been trying to run the koha-auth facility that is supposed to generate authority records. See below error from my code inveniouser@inveniosrv:~/.cpanm/work/1439883119.26275/Koha-Contrib-Tamil-0.040/share/etc$ sudo koha-auth create_from_biblio /home/inveniouser/.cpanm/work/1439879750.23982/Koha-Contrib-Tamil-0.040/share/etc/auth-marc21.conf authorities.txt Create authorities from biblio records source: Koha DB target: authorities.txt temporary file: authorities.txt.b5er Start process... Can't use an undefined value as an ARRAY reference at /usr/local/share/perl/5.14.2/Koha/Contrib/Tamil/Authority/FromBiblioTask.pm line 58 (#1) (F) A value used as either a hard reference or a symbolic reference must be a defined value. This helps to delurk some insidious errors. Uncaught exception from user code: Can't use an undefined value as an ARRAY reference at /usr/local/share/perl/5.14.2/Koha/Contrib/Tamil/Authority/FromBiblioTask.pm line 58. Any assistance would be appreciated. Best Regards, -- Solomon Mwangi Cell:+254 715 502349 Skype: solomon.mwangi Website: http://soqko.com
