Hello,
i tred to split a string and work with a each loop, but i unable to return the array. You can see my source test code for this.

public class HandlebarsHelpers
{
    public static void RegisterHelpers()
    {
        Handlebars.RegisterHelper("stringToArray", (writer, context, parameters) =>
        {
            if (parameters.Length != 1 || parameters[0] == null)
            {
                throw new ArgumentException("stringToArray helper requires exactly one string parameter.");
            }

            string inputString = parameters[0].ToString();
            var resultArray = inputString.Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

            writer.WriteSafeString("[");
            for (int i = 0; i < resultArray.Length; i++)
            {
                writer.WriteSafeString($"\"{resultArray[i].Trim()}\"");
                if (i < resultArray.Length - 1)
                {
                    writer.WriteSafeString(",");
                }
            }
            writer.WriteSafeString("]");
        });
    }
}

    public static class hadlebartest
    {
        public static void handeltest()
        {
            // Registrierung der Helper
            HandlebarsHelpers.RegisterHelpers();

            // Beispiel-Handlebars-Template
            var source = @"
        
        <ul>
            {{#each (stringToArray inputString)}}
                <li>{{this}}</li>
            {{/each}}
        </ul>";

            var template = Handlebars.Compile(source);

            // Kontext-Daten
            var data = new
            {
                inputString = "apple, banana, cherry"
            };

            // Rendern des Templates mit den Daten
            var result = template(data);

            Console.WriteLine(result);

            // The result shoud be
            /*
            <ul>
            <li>apple</li>
            <li>banana</li>
            <li>cherry</li>
            </ul>
            */

            // My Result is
            //< ul >
            //    < li > 27 </ li >
            //</ ul >

            //its the length of the string
        }
    }

I use .net 8 with Handlebars.Net 2.1.6
