Fixed – The ‘CreateMultiple’ method does not support entities of type ‘none’. MessageProcessorCache returned MessageProcessor.Empty in Dataverse / Dynamics 365

Recently while trying to use the new CreateMutipleRequest message we got the below error – “The ‘CreateMultiple’ method does not support entities of type ‘none’. MessageProcessorCache returned MessageProcessor.Empty” It was because we were not populating the EntityName property of EntityCollection class. Specifying it fixed the issue. Hope it helps..
