Error : Unable to determine composite primary key ordering

[Peter-Shawky]

Thanks for this great tool
But i got an error while trying to test the CSV sample data to import it in our Rock RMS but unfortunately I got the current error message :
System.InvalidOperationException: 'Unable to determine composite primary key ordering for type 'Rock.Model.GroupLocationScheduleConfig'. Use the ColumnAttribute or the HasKey method to specify an order for composite primary keys.'
This exception was originally thrown at this call stack:
[External Code]
Bulldozer.CSV.CSVComponent.LoadExistingData(string) in CSVComponent.cs
Bulldozer.CSV.CSVComponent.TransformData(System.Collections.Generic.Dictionary<string, string>) in CSVComponent.cs
