# scripting

Hi all, I am trying to pass an argument to a KotlinScript (1.3.72) but it seems the generated script class has only a default constructor

@KotlinScript(
    fileExtension = "siteCost.kts", 
    compilationConfiguration = SiteCostScriptCompilationConfiguration::class,
    evaluationConfiguration = SiteCostScriptEvaluationConfiguration::class
)
abstract class SiteCostScript(val arg: String)

for the time being, the constructor arg is directly passed in the `EvaluationConfiguration`:

object SiteCostScriptEvaluationConfiguration : ScriptEvaluationConfiguration({
    constructorArgs("hugo")
})

however, if the script is evaluated using the following code

fun <T> eval(scriptString: String, resultClass: Class<T>): T {
        val jvmScriptingHost = BasicJvmScriptingHost().eval(
            scriptString.toScriptSource(),
            SiteCostScriptCompilationConfiguration,
            SiteCostScriptEvaluationConfiguration
        )
        return (resultWithDiag.valueOrThrow().returnValue as ResultValue.Value).value as T  
    }

I get an Exception (abbreviated)

java.lang.RuntimeException: java.lang.IllegalArgumentException: wrong number of arguments

	at kotlin.script.experimental.jvm.BasicJvmScriptEvaluator.evalWithConfigAndOtherScriptsResults(BasicJvmScriptEvaluator.kt:95)

It seems BasicJvmScriptEvaluator.evalWithConfigAndOtherScriptsResults tries to invoke a default constructor (without args) which does not exist.

What am I doing wrong? Am I supposed to implement my own ScriptEvaluator?

I found it … using `BasicJvmScriptingHost().evalWithTemplate<SiteCostScript>`and removing the two configurations from the `SiteCostScript`class resolved the issue
