Suggested Fixes

  • Make sure that if you have a discriminator set for a model, then an explicit discriminator field/property definition is also added in the same model's fields/properties.
  • The name of the discriminator property/field must exactly match the name of the discriminator set in the model/type definition.
  • Only a string typed discriminator property/field is currently supported.
