Hello @truongvietgroup

The error is that your $matches array doesn't have anything on index 1. (So your pattern didn't match)

You can prevent the error by checking if $matches[1] exist.

protected function getDateFromLine($line)
{
    preg_match('/^[([^\]]+)]/', $line, $matches);
    
    if (isset($matches[1])) {
        // we have an result
        return Carbon::createFromFormat('D M d H:i:s Y', $matches[1]);
    }
    // Return what you want if there isn't anything available.
    return Carbon::now();
}

ps. I have update your post to get some code blocks.
