Custom Data Adapter's Cannot handle Guid types For Delete

I created a custom adapter and it seems to work except for my override of RemoveAsync. The error I get in Chrome is: 

blazor.server.js:8 Uncaught (in promise) Error: System.InvalidCastException: Invalid cast from 'System.String' to 'System.Guid'.
   at System.Convert.DefaultToType(IConvertible value, Type targetType, IFormatProvider provider)
   at System.String.System.IConvertible.ToType(Type type, IFormatProvider provider)
   at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider)
   at System.Convert.ChangeType(Object value, Type conversionType)
   at Syncfusion.EJ2.Blazor.BaseAdaptor.BaseRemove(String baseData, String keyField, String key)
    at Object.endInvokeDotNetFromJS (blazor.server.js:8)
    at e.<anonymous> (blazor.server.js:8)
    at blazor.server.js:1
    at Array.forEach (<anonymous>)
    at e.invokeClientMethod (blazor.server.js:1)
    at e.processIncomingData (blazor.server.js:1)
    at e.connection.onreceive (blazor.server.js:1)
    at WebSocket.i.onmessage (blazor.server.js:1)

This dies without getting back to my code.

Thank you,

John
