RPXLib.dll throwing the exception The remote server returned an error: (500) Internal Server Error

Question

I am trying to build the site login facility as single sign on. some how I come across to the site Janrain where I found the API's to do so. also I am trying this in my asp.net MVC application. so that I was following the steps given over here I followed exact steps what are given, so I think no need to give code here. But In my action as:

public bool signin(string token)
        {
           // string token = token_url;
            RPXLib.RPXService service = new RPXLib.RPXService(new RPXLib.RPXApiSettings("https://singlesignontest.rpxnow.com/api/v2/auth_info", "56fd9a76a5da4dffb9a437fe09564544b209c622"));
            try
            {
                RPXLib.Data.RPXAuthenticationDetails userDetails = service.GetUserData(token); //*Exception here* 
                return true;
            }
            catch (RPXLib.Exceptions.RPXAuthenticationErrorException ex)
            {
            } return false;
        }

I am getting exception at denoted line of code. I am getting token value properly. but could not proceed a head. Exception is :

The remote server returned an error: (500) Internal Server Error.

Stack Trace:

Answer 1

i acctually had the same issue now and solved it. I am using their helper c# class and the path /api/v2/ is hard coded there. So you cant have that path in th https://rpxnow.come/api/v2/ string also, which is a inparam to the new Rpx() call. So just send in the url without the /api/v2/ to the new Rpx() call. Solved it for me.

Good luck!
