“有些不对劲——可能缺少 \item”，带有部分个性化目录（titletoc）

Question

我希望每个章节都以个性化的部分目录开始（我使用 titletoc 实现了这个功能）。

当我编译时出现以下错误：

出了点问题——可能缺少了 \item

我已经完成了 MWE：

    \vspace{-3mm}
    \hrulefill
}
\section{Context}\label{sec-context}
This chapter introduces the context of the project
\stopcontents[Introduction]
\end{document}

我已经进行了一些调查，当在部分目录（在本例中）第一个目录之前有要打印的内容时，会出现此错误\hrulefill。如果直接有\printcontents命令，则不会出现错误。

如果我删除个性化的 TOC 样式，则不会出现错误。

我已经在其他文档中使用了这种样式（没有部分目录），并且效果很好...

该错误将我重定向到包含以下内容的 main.ptc 文件：

\babel@toc {english}{}
\ttl@starttoc {Introduction@1}
\contentsline {chapter}{\numberline {1}Introduction}{2}{chapter.1}%
\contentsline {section}{\numberline {1.1}Context}{2}{section.1.1}%
\ttl@stoptoc {Introduction@1}
\contentsfinish  

你们有人知道它是从哪里来的吗？
