I'm trying to run this as a standalone project in Overleaf but it does not run to generate a graph like this.

enter image description here

Could anyone help with this?

\documentclass{standalone}
\usepackage[utf8]{inputenc}
\usepackage{fourier, cabin}
\usepackage{pstricks-add, pst-eucl}
\usepackage{auto-pst-pdf}

\begin{document}

This is a reproduction of the original figure with two \draw commands and without libraries. The arrows are placed on the segments to make it easier to position them, and to avoid libraries. Maybe this compiles for you.

\documentclass[tikz,border=3mm]{standalone}
\usepackage{amsmath}
\begin{document}
\begin{tikzpicture}[pics/arrow/.style={code={\draw[very thick,-stealth] 
    (0,0) --(0.5,0);}},declare  function={r=1;R=5;h=0.4;alpha(\x)=180-asin(h/\x);},
    s/.style={sloped,allow upside down,pos=#1},s/.default=0.5]
 \draw[very thick] ({alpha(r)}:r) arc[start angle={alpha(r)},
    end angle={-alpha(r)},radius=r] node[pos=0.5,above right]{$J$}
    -- pic[s]{arrow} ({-alpha(R)}:R) node[left]{$L$}
    arc[start angle={-alpha(R)},end angle=-45,radius=R] pic[s]{arrow}
    node[below=2pt]{$A$} node[above right]{$\alpha-\mathrm{i}\mathsf{T}$}
    -- pic[s=0.6]{arrow} (45:R) 
    node[above=2pt]{$B$} node[below right]{$\alpha+\mathrm{i}\mathsf{T}$}
    arc[start angle=45,end angle={alpha(R)},radius=R] pic[s=0.75]{arrow}
    node[left]{$E$}
    -- pic[s=0.6]{arrow} cycle;     
 \draw (-R-1,0) -- (R+1,0) node[right]{$\boldsymbol{x}$}
  (0,-R-1) -- (0,R+1) node [above]{$\boldsymbol{y}$} 
  (-90:R) node[below left]{$N$}
  (90:R) node[above right]{$D$}
  (0,0) edge[edge label={$R$}] (135:R)
   node[below left]{$O$}-- coordinate (aux) (45:r)
   (aux) to[bend left] ++ (60:1) node[right]{$\varepsilon$}
   (r,0)node[above right]{$J$}; 
\end{tikzpicture}
\end{document}
