I am getting an error with the C# ComboCurve library calling the GetAllEconModelsV2 method. Here is the error that is getting returned.

Error converting value “Operations” to type ‘System.Nullable`1[ComboCurve.Api.Model.EconModel+EconModelTypeEnum]’. Path ‘[46].econModelType’, line 1, position 20180.
