Hi all,

Has anyone faced this exception and how to fix it?

Exception thrown:
System.TypeInitializationException: The type initializer for 'Skyline.Protocol.PowerShellApi.Commands.CommandMapper' threw an exception. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
   at System.Reflection.RuntimeModule.GetTypes(RuntimeModule module)
   at System.Reflection.RuntimeModule.GetTypes()
   at System.Reflection.Assembly.GetTypes()
   at Skyline.Protocol.PowerShellApi.Commands.CommandMapper..cctor()
   --- End of inner exception stack trace ---
   at Skyline.Protocol.PowerShellApi.Commands.CommandMapper.GetMappedCommands()
   at Skyline.Protocol.ProtocolApi.Controllers.CommandsConfigurationController.OnInitialization(SLProtocol protocol)
   at QAction.Run(SLProtocol protocol)

This happened after the Nuget migration.
I tried to catch System.Reflection.ReflectionTypeLoadException exception, but without success.

Hi Elmaza,

These errors sometimes happened in our environments and fixed by the following operation.

  1. Stop DataMiner
  2. Remove Skyline DataMiner\Scripts\*.txf files
  3. Remove all file in Skyline DataMiner\Scripts\Compiled folder
  4. Start DataMiner

I hope these solve your issues.
