_options_prepare_options() error after drupal core update

[tubia]

Hi,
I updated drupal core and modules after installing deskulu. Everything works except for the error below, reported a dozen of times at the beginning of the ticket/new page.

Notice: Undefined index: strip_tags_and_unescape in _options_prepare_options() (line 282 of /var/www/html/deskulu/modules/field/modules/options/options.module).

Any hint on what this could be?

Same here.
