   I have this code in my worker file which i trigger but this method dose not sending the selected data to up

    _selectRandomQuestion(){
           // get random number base on the question length
           const randomIndex=Math.floor(Math.random()*this.#match_question.length)
           // storing selected question
           this.#_selectedQuestion=this.#match_question[randomIndex]
           console.log('selected question =>')
           console.log(this.#_selectedQuestion)
           // removing selected question from array
           this.#match_question.splice(randomIndex,1)
           // sends selected question out of worker
           return parentPort.postMessage({
               "E":quizGameEventNames.NEXT_QUESTION,
               "D":{
                   "data":{
                       "question":this.#_selectedQuestion
                   }
               }
           })
       }
       ```
       the worker.on("message") dosen't get anything why?
