When I add new localization (which not manually added for the game) in the requesting JSON (https://developers.google.com/games/services/publishing/api/achievementConfigurations) for updating achievements or leaderboards the server return following error:
{
"error": {
"errors": [
{
"domain": "global",
"reason": "UnsupportedLocale",
"message": "The locale bg in the name field is not supported by the application."
}
],
"code": 400,
"message": "The locale bg in the name field is not supported by the application."
}
}
Please help me to solve this issue
