How to insert DateTime (or DateTime2) with Dapper?

I'm trying to do the following:

var p = new DynamicParameters();
p.Add(...);
p.Add(...);
// ideally I want to insert null for end date, but I also tried DateTime.MinValue
// or some other date, but doesn't help
p.Add("@endDate", null, DbType.DateTime, ParameterDirection.Input);
using (var con = new SqlConnection(ConnectionString))
{
    // stored procedure does 'select SCOPE_IDENTITY()' to return the id of inserted row.
    int id = con.Query<int>("StoredProcedureName", p, commandType: CommandType.StoredProcedure).First();
}

This is throwing "InvalidCastException" and I believe this is becase of the date. I previously had datetime2(20) for the endDate in the sql db, changed it to datetime to see if it fixes it, but doesn't. Can anyone help?

The invalid cast here is that SCOPE_IDENTITY() actually returns decimal. The parameters are working fine.
