Probably missing something, but where does parsePreferredLocale() actually get called from? I don’t see it in any base classes and nothing in Feed Me’s User element calls it.

[i-just]

services/Process->processFeed() calls base\Element->parseAttribute() which calls a method called 'parse' . ucwords($fieldHandle). That’s how most attributes are dealt with.

just i was confused about the fieldname PreferredLocale, that is the functionname but in my csv it is working fine in my moodle [4.1.6 (Build: 20231009)] perfect if i have a field lang with the isocode
en, fr, ro, ru, etc
