I use the following code using the tikz-feynman package.

\tikzfeynmanset{
    every vertex/.style={red, dot},
    every particle/.style={blue},
    every blob/.style={draw=green!40!black, pattern color=green!40!black},
}
\feynmandiagram [horizontal=a to b] {
    a [particle={\(\gamma, Z\)}] -- [boson] b [blob],
    c -- [fermion] b -- [fermion] d,
};

However, I get an output in which the lines are drawn haphazardly.

Is there a way to correct this?
