Description:

Hi,
i want to change the userlanguage of a user via API-call.
Here is my example call (i added convertAsciiEmoji for testing purposes)::

https://${"host"}/api/v1/users.setPreferences/api/v1/users.setPreferences
{"userId": "xxxxxxxxxxxx","data": { "language": "da", "convertAsciiEmoji":true}}`

And this is the response:

{"user":{"_id":"xxxxxxxxxxxx","settings":{"preferences":{"convertAsciiEmoji":true}}},"success":true}

The language in the response is missing, and the language didn't changed.
The setting convertAsciiEmoji was changed by the API-Call

Steps to reproduce:

See description

Expected behavior:

The API should change the language

Actual behavior:

The API doesn't change the language
