[brodrigz]

Passing an IDictionary<string,object> to .AsInsert() seems to result in an unhandled NullReferenceException
SqlKata 2.4.0
SqlKata.Execution 2.4.0

Example:

            IDictionary<string, object> obj = new ExpandoObject();
            obj.Add("col1", "value");
            QueryFactory queryFactory = new();
            queryFactory.Query("tableName").AsInsert(new[] {obj}).Get(); //throws error
