I have been trying for a while now but each time, the same error messages show up.
! LaTeX Error: Something's wrong–perhaps a missing \item.
What I'm trying to achieve is to merely insert the Abstract as a part of the table of contents.

Best Answer
You're using the
article
document class, which doesn't usechapter
headings. This is what is causing the error. Therefore, change\addcontentsline{toc}{chapter}{abstract}
to\addcontentsline{toc}{section}{abstract}
Additionally, if you want 'Abstract' with a capital A. Then use
\addcontentsline{toc}{section}{Abstract}
