I am having an issue in my production environment this worked fine in a test lab but not production Solarwinds.
The error in the discovery is
A Network Discovery job has failed to complete.\r\nState: Failed\r\nProfile id: 106.\r\nThe Job Scheduler is reporting the following error:\r\nSolarWinds.JobEngine.WorkerProcess.JobExecutionException: System.Exception: Unable to deserialize job description. ---> System.Runtime.Serialization.SerializationException: Error in line 0 position 0. Element 'http://schemas.datacontract.org/2004/07/SolarWinds.Orion.Core.Models.Discovery:DiscoveryPluginJobDescriptionBase' contains data from a type that maps to the name 'http://schemas.solarwinds.com/2008/DeviceStudio:DeviceStudioDiscoveryPluginJobDescription'. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to 'DeviceStudioDiscoveryPluginJobDescription' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.
