REST API - Network Sonar Discovery Gets Created, but fails to complete

Question

Hello Orion SDK Community,

I have automation in place that is working to create discoveries, run the discovery, and complete the import - I have this working fine in multiple instances of solarwinds.

However in one specific instance (which is on the same version of NPM and all other modules) I'm getting a few random errors. Any help would be greatly appreciated.

One set of weird errors:

2017-08-22 15:58:54,105 [85] ERROR SolarWinds.Orion.Core.SharedCredentials.CredentialDAL - (null) (null) Unable to find credential with ID = 3, owner = and credentialType = SolarWinds.Orion.Core.SharedCredentials.Credentials.UsernamePasswordCredential

2017-08-22 15:59:35,215 [17] ERROR SolarWinds.InformationService.Core.InformationService - (null) (null) Exception for Operation: <root type="array">

</root>

I should note that CredentialID 3 is type: SolarWinds.Orion.Core.Models.Credentials.SnmpCredentialsV2 NOT SolarWinds.Orion.Core.SharedCredentials.Credentials.UsernamePasswordCredential,

so I'm wondering why it is being interpreted as a different type.

Here is the statusdescription as reported by Orion.DiscoveryProfiles - I'm not suer why it is referencing "DeviceStudioDiscoveryPluginJobDescription" when I only am using the Core, Interface, and VIM Plugins....

Network Discovery job has failed to complete.\r\nState: Failed\r\nProfile id: 28.\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 if you are using DataContractSerializer 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 the serializer.

Thank you,

There is bug in the product. Discovery using SWIS verbs does not work on additional poller if main poller and additional poller have different installation paths. I created internal bug for this, we track it under CORE-9287.

Unfortunately currently there is no proper workaround.

Currently the only fix is to re-install AP and install Orion into same location as on MP.

Example:

Main poller install path is e:\Program Files (x86)\SolarWinds\

All APs have to be installed on same path: e:\Program Files (x86)\SolarWinds\, otherwise discovery through SWIS does not work.
