缺少字符：nullfont 中没有分号

我的目标是“干净”的编译，这就是为什么我想Missing ; in nullfont在以下 MWE 中消除这个问题。一切都编译得很好，但有多达 5 个Missing character: There is no ; in nullfont警告，我从以前的问题中知道，这通常是由 TikZ 代码中多余的“；”引起的。然而，我在我的代码中没有看到问题。

第一个是Fig01.tikz：

\begin{tikzpicture}
%\font\nullfont=cmr10
\newcommand\bulkCoordinates[0]{
        \coordinate (ex) at (10ex,0);
        \coordinate (v1) at (origin);
        \coordinate (v2) at ($(v1)!1!-135:(ex)$);
        \coordinate (v9) at ($(v1)!1!-45:(ex)$);
        \coordinate (v8) at ($0.5*(v2)+0.5*(v9)$);
        \coordinate (v3) at ($(v2)!1!-120:(v8)$);
        \coordinate (v7) at ($(v2)!1!-60:(v8)$);
        \coordinate (v10) at ($(v9)!1!60:(v8)$);
        \coordinate (v11) at ($(v9)!1!120:(v8)$);
        \coordinate (v4) at ($(v3)!0.8!-115:(v7)$);
        \coordinate (v6) at ($(v3)!0.8!-55:(v7)$);
        \coordinate (v5) at ($0.5*(v4)+0.5*(v6)$);

            {\node[mystyle,fill=podo02,text=white] (V\x) at (v\x) {\x}}

通过阅读日志，我标记了OFFENDING LINE暗示问题的地方。

问题出在

    \foreach \x in {1,2,3,4,6,7,8,9,10,11} {
        \ifthenelse{\x = 1 \OR \x = 2 \OR \x = 4 \OR \x = 6 \OR \x = 10}
            {\node[mystyle,fill=podo02,text=white] (V\x) at (v\x) {\x}}
            {}
            ;

对于非选择的情况，有一个分号。

    \foreach \x in {1,2,3,4,6,7,8,9,10,11} {
        \ifthenelse{\x = 1 \OR \x = 2 \OR \x = 4 \OR \x = 6 \OR \x = 10}
            {\node[mystyle,fill=podo02,text=white] (V\x) at (v\x) {\x};}
            {}
