Evaluation of array.filter with function pointer not working

Using the exampe template from the documentation of array.filter:

var result = Template.Parse("{{['', '200', '','400'] | array.filter @string.empty}}").Replace(new TemplateContext());

The above gives the desired result:

["", ""]

Using Evaluate instead of Replace:

var result = Template.Parse("{{['', '200', '','400'] | array.filter @string.empty}}").Evaluate(new TemplateContext());

returns an object of type ScribanRange. When trying to iterate the items in result, i get the following exception:

Value cannot be null. (Parameter 'callerContext')
  at Scriban.Syntax.ScriptFunctionCall.Call(TemplateContext context, ScriptNode callerContext, IScriptCustomFunction function, ScriptArray arguments)
  at Scriban.Functions.ArrayFunctions.FilterInternal(TemplateContext context, SourceSpan span, IEnumerable list, IScriptCustomFunction function, Type destType)+MoveNext()
  at Scriban.Runtime.ScriptRange.GetEnumerator()+MoveNext()

Expectation would be to either be able to iterate over the result or directly getting an array or list as a result. Am I doing anything wrong here?
