I create a telegram bot, which collects user info into gSheets. I want to create a filter. If the user wrote less than 10 symbols, bot says that this is not enough. When I tested it, bot just stopped, but JSON was still coming and being processed.

  function doPost(e) {
    let contents = JSON.parse(e.postData.contents); 
    let chat_id = contents.message.chat.id; 
    let text = contents.message.text; 
  
    if (text.length > 10) {
      sendText(chat_id,"✅ Great!");
    }
    else (text.length < 10) {
      sendText(chat_id,"😔 Its not enough.");
    }
  }
