Hi Solomon, it looks like you are using a tool from here: https://metacpan.org/release/Koha-Contrib-Tamil These tools are not part of Koha, so it might be better if you report any problems using the issue tracker on the CPAN site. Hope this helps, Katrin Am 12.01.2016 um 08:25 schrieb Solomon Mwangi:

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,
