cant_update_item when i edit acf user’s fields by API

Hi,

When i try to edit fields of a user i have the error :
{“code”:”cant_update_item”,”message”:”Cannot update item”,”data”:{“status”:500}}

My endpoint is : wp-json/acf/v3/users/(ID)

I use PUT method.

After few hours I found something really weird that make it works but i can’t use this forever :
I need to put a rule in my ACF configuration like :
OR
USER ACTUEL – IS – CONNECTED
This configuration add all the ACF fields for all elements (post, custom post type…), but let the UPDATE works through the API.
The problem is, i can’t let this fields everywhere. So i need to find a solution

How can i do this ?

Thanks
