Hi there.
After batch update some itemes (to add them to a newly created ItemSet), the ItemSet menu (from the admin interface) does not display anything and gives this error: Omeka S encountered an error
In the apache error log I have this:
[Mon Sep 07 12:37:12.276819 2020] [php7:notice] [pid 1776] [client 10.1.1.15:33114] PHP Notice: Undefined offset: 0 in /var/www/***********************/application/src/Api/Representation/ItemSetRepresentation.php on line 70, referer: https://**********************/admin/item
I have a production installation of omeka s 3 years old now. Here is the system information table:
