Answer 1

By the logic, i will tell "i" go to far away, but to be sure to not have any error, juste check if newData.articles[i].source.name is defined in a "if", if it's true, you assigned to your variables and send the message, if not, just go next

Answer 2

First Check the newData.articles[i].source is defined

Change Your for loop Like this

    for(let i =0;i<itr;i++){
      if(newData.articles[i]&&newData.articles[i].source){
        let name=newData.articles[i].source.name||"Noname",
        title=newData.articles[i].source.title||"No Title",
        description=newData.articles[i].description||"No Description";
        bot.sendMessage(chatId,`${name}\n\nTitle : ${title}\n\nDescription : ${description}`)
      }       
    }
