SmartEnum not deserialized as path parameter

[BrianFreemanAtlanta]

I have a controller that uses SmartEnum as a path parameter:

[HttpGet]
        [Route("{clientApiIdentifier}/FilterListSmart/{columnId}")]
        public async Task<List<dynamic>> GetFilterListSmart(
            [FromRoute] string clientApiIdentifier,
            [FromRoute] FormsReportColumnsSmart columnId)

When I call my controller it doesn't deserialize the value for columnId. columnId is always "Unknown". example call: {{ReportingApiUrl}}/Forms/{{clientId}}/FilterListSmart/CandidateId

I tried a test case calling deseriallize on a string and "AssignedTo" works but AssignedTo doesn't. Am I missing something? or is this an issue?

Initially I got errors from MVC binding for abstract class and parameterless constructor needed. I ended up with this class:

    [JsonConverter(typeof(SmartEnumValueConverter<FormsReportColumnsSmart, int>))]
    public class FormsReportColumnsSmart : SmartEnum<FormsReportColumnsSmart>
