I've installed Appian Web parts for Sharepoint in Sharepoint Server. When I try to login with Appian Username/Password from Sharepoint, it displays below error:

Error occurred in WebPart rendering:System.ArgumentNullException: Value cannot be null. Parameter name: value at Newtonsoft.Json.JsonConvert.DeserializeObject[T](String value, JsonSerializerSettings settings) at Appian.AppianPart.AppianPart.CheckUserAccess() at Appian.AppianPart.AppianPart.CreateChildControls()

Any suggestions??

Thanks in advance!!

It appears you have not given your Appian user enough permissions to render the homepage. Either that or you have a permissions issue on the file system of your Sharepoint server ... definitely permissions related.

We have provided both farm Admin & Site collection admin permissions to the User, yet the above error still persists! Is there any other specific settings/configurations to be done?
