Hello Arron.
Can you make a screen shot of before mapping event ?

We were hoping that you could find mistake in your code by yourself.
You have changed task to msg, msg to BQ_status, but forget to change it everywhere, thus BQ_status is always empty, and there is no property with name header in it.
Your mistake is here:
msg = msgssArr.shift();

Hi Murali.
1) It is better to ask questions in one post, so we can track issues handling progress for your project.
2) You have implemented styles that will hide your element.
