[facebook] Facebook Graph API error code list

Where can I find the official Graph API Error Code list?

I have been using the Graph API for half a year, and in the past 6 months, the error code's format has changed twice!

The first time I saw the error code, it looks like:

{   
    "error": {
        "message": "Error invalidating access token: The session has been invalidated because the user has changed the password.",      
        "type": "OAuthException",      
    }
}

It's really stranger, the error message didn't provide any error code!

And then several months later, the "expected" error code was introduced.

{   
    "error": {
        "message": "Error invalidating access token: The session has been invalidated because the user has changed the password.",      
        "type": "OAuthException",      
        "code": 190,      
    }
}

But sadly, you still cannot distinguish what the error exactly is by checking the "code", since many errors with the same "type" have the same "code".

Just now, I found the error message contains new field:

{   
    "error": {
        "message": "Error invalidating access token: The session has been invalidated because the user has changed the password.",      
        "type": "OAuthException",      
        "code": 190,      
        "error_subcode": 460   
    }
}

OK, it's just what I need.

But where can I find the error code list? I knew there is FQL error code list, http://fbdevwiki.com/wiki/Error_codes#FQL_Errors, but it seems out of date and does not provide any message about the "error_subcode".

I have also found some more error subcodes, in case of OAuth exception. Copied from the facebook bugtracker, without any garantee (maybe contain deprecated, wrong and discontinued ones):

/**
  * (Date: 30.01.2013)
  *
  * case 1: - "An error occured while creating the share (publishing to wall)"
  *         - "An unknown error has occurred."
  * case 2:    "An unexpected error has occurred. Please retry your request later."
  * case 3:    App must be on whitelist        
  * case 4:    Application request limit reached
  * case 5:    Unauthorized source IP address        
  * case 200:  Requires extended permissions
  * case 240:  Requires a valid user is specified (either via the session or via the API parameter for specifying the user."
  * case 1500: The url you supplied is invalid
  * case 200:
  * case 210:  - Subject must be a page
  *            - User not visible
  */

 /**
  * Error Code 100 several issus:
  * - "Specifying multiple ids with a post method is not supported" (http status 400)
  * - "Error finding the requested story" but it is available via GET
  * - "Invalid post_id"
  * - "Code was invalid or expired. Session is invalid."
  * 
  * Error Code 2: 
  * - Service temporarily unavailable
  */

While there does not appear to be a public, Facebook-curated list of error codes available, a number of folks have taken it upon themselves to publish lists of known codes.

Take a look at StackOverflow #4348018 - List of Facebook error codes for a number of useful resources.

I was looking for the same thing and I just found this list
