[Tex/LaTex] Argument of \begin has an extra }. \par

Question

I keep getting this up and I don't see the issue

Argument of \begin has an extra }.
<inserted text> 
                \par 
l.78 \item
           <Item 1>

This is the doc

\section{Previous Jobs}
\cventry{2011 --}{Teacher}{\textsc{Text}}
\begin{itemize}
\item Item 1
\item Item 2
\item Item 3
\item Item 4
\item Item 5
\item Item 6
\item Item 7
\item Item 8
\end{itemize}

Answer 1

Command \cventry is defined to have 6 arguments, and arguments 3 to 6 can be left empty (but you have to write {}):

\cventry{year--year}{Degree}{Institution--3}{City--4}{\textit{Grade}--5}{Description--6}  % arguments 3 to 6 can be left empty 

With the following MWE (I added the missing {}, see marked code with <======)

\documentclass[11pt,a4paper,sans]{moderncv}

\moderncvstyle{classic} % casual, classic, banking, oldstyle and fancy
\moderncvcolor{blue} 

\usepackage[utf8]{inputenc}

\usepackage[scale=0.75]{geometry}

\cventry{year--year}{Degree}{Institution}{City}{\textit{Grade}}{Description}

\section{Previous Jobs}
\cventry{2011 --}{Teacher}{\textsc{Text}}{}{}{} % <=====================
\begin{itemize}

\item Item 2
\item Item 3
