    If dataItem.message’s type is anything but a string. The substring won’t help.
    Try to
    console.log(dataItem.message)
    And see what type it is.
    Otherwise it’ll be tough to help much more without also seeing where dataItem is created and updated in your code.

    Instead of passing the substrings as an argument to dataItem.message. I will suggest you use slice method. so instead of using dataItem.message.substring(0, 20) use dataItem.message.slice(0,20). I hope this helps!
