Common Error Code

Status Codes

Code	Name	Description
40206	MISSING_IDENTITY_ERROR	The identity does not exist on the server and forceCreate was false [and a profileId was provided - otherwise 40208 would have been returned]. Will also occur when forceCreate is true and a saved [but un-associated] profileId is provided. The error handler should reset the stored profile id (if there is one) and re-authenticate, setting forceCreate to true to create a new account. A common cause of this error is deleting the user's account via the design portal.
40207	SWITCHING_PROFILES	Indicates that the identity credentials are valid, and the saved profileId is valid, but the identity is not associated with the provided profileId. This may indicate that the user wants to switch accounts in the app. Often an app will pop-up a dialog confirming that the user wants to switch accounts, and then reset the stored profileId and call authenticate again.
40208	MISSING_PROFILE_ERROR	Returned when the identity cannot be located, no profileId is provided, and forceCreate is false. The normal response is to call Authenticate again with forceCreate set to true.
40217	UNKNOWN_AUTH_ERROR	An unknown error has occurred during authentication.
40307	TOKEN_DOES_NOT_MATCH_USER	The user credentials are invalid (i.e. bad gameCenterId)
