Hi Mehah! I appreciate your thorough reviews to push this effort further and get it merged. I am planning to resolve the issue by removing the quotation marks and maybe separating the setters into different lines further if that doesn't work. In my local environment it is working fine. Can you suggest an approach to resolve this?

@tornadia From what I understand, these errors are syntax errors, I'll see if @dudantas or @beats-dh can help you.
