[Solved] I used a workaround to fix this, by adding a custom JsonConverterAttribute <JsonConverter(GetType(ClaimsConverter))> to Claims() IdentityUser Class Property.

[VB.net]
<JsonConverter(GetType(ClaimsConverter))>
Public Property Claims() As ICollection(Of Claim)

'With ClaimsConverter as a custom class inheriting from JsonConverter like so:

[VB.net]
Class ClaimsConverter
Inherits JsonConverter
Public Overrides Function CanConvert(objectType As Type) As Boolean
Return (objectType = GetType(System.Security.Claims.Claim))
End Function

Public Overrides Function ReadJson(reader As JsonReader, objectType As Type, existingValue As Object, serializer As JsonSerializer) As Object
    Dim result As New Collection(Of Claim)

    Dim jo As JArray = JArray.Load(reader)
    For Each obj As JObject In jo
        Dim type As String = obj("type")
        Dim value As String = obj("value")
        Dim valueType As String = obj("valueType")
        Dim issuer As String = obj("issuer")
        Dim originalIssuer As String = obj("originalIssuer")
        result.Add(New Claim(type, value, valueType, issuer, originalIssuer))
    Next
    Return result

End Function

Public Overrides ReadOnly Property CanWrite() As Boolean
    Get
        Return False
    End Get
End Property

Public Overrides Sub WriteJson(writer As JsonWriter, value As Object, serializer As JsonSerializer)
    Throw New NotImplementedException()
End Sub

End Class

Works like a charm; hope it help

from couchbase-aspnet-identity.
