App Management Service for Sharepoint 2013 SP Desinger Workflows

I've created SP 2013 simple workflow using SP Designer 2013. I've set up my environment as described in msdn documentation. But when I'm trying to deploy the solution I'm receiving following exception:

Microsoft.SharePoint.SPEndpointAddressNotFoundException: There are no addresses available for this
application.
   at Microsoft.SharePoint.SPRoundRobinServiceLoadBalancer.BeginOperation()
   at Microsoft.SharePoint.Administration.SPServiceApplicationProxyBase`1.ExecuteOnChannel(Boolean
requireDelegation, Action`1 codeBlock)
   at Microsoft.SharePoint.AppManagement.AppManagementServiceApplicationProxy.GetScaleOutDatabaseMap()
   at Microsoft.SharePoint.SPScaleOutDatabaseMap.GetMapCacheEntries

Solution:

Just resolved.

I found following message in ULS:
"There are no instances of the App Management Service started on any server in this farm. Ensure that at
least one instance is started on an application server in the farm using the Services on Server page in
Central Administration."
I went to CA -> System Settings -> Services on server and started App Management Service. Then performed
iisreset and the workflow deployed successfully.
