ZOHOCRMSDK-6.0 Token issue

Hi I get an error regarding tokens when want to retrieve a record.

i have a class constructor which contains this :

new SDKInitializer.Builder()

.Environment(environment)

.Token(token)

.Store(tokenstore)

.SDKConfig(config)

.ResourcePath(resourcePath)

.Logger(logger)

//.RequestProxy(requestProxy)

.Initialize();

during processing it calls this line which causes the error : Com.Zoho.Crm.API.Util.APIResponse<Com.Zoho.Crm.API.Record.ResponseHandler> responseGet = recordOperations.GetRecordUsingExternalId("3163", new ParameterMap(), headerInstance);

errorlog :
