API - Updating service returns error

Has anyone managed to successfully curl a service to update?

I have attempted to update a service as described in the following “Upgrade Rancher Service using REST API”.

I am curling using the API upgrade but i get an error of LaunchConfig/secondaryLaunchConfigs need to be specified for inService strategy.

Any help would be much appreciated
