获取有关 aa latex 错误的更多上下文

我正在尝试运行 Beamer 以获取演示文稿中的列表。我收到了一条神秘的错误消息,如下所示:

! Missing number, treated as zero.
<to be read again> 
               \let 
l.221 \end{frame}

? H
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
 look up `weird error' in the index to The TeXbook.)

我的问题部分在于我的代码中没有 \let,这肯定是宏的扩展。我立即想到的问题是“当 TeX 遇到错误时,我如何才能让它告诉我它正在扩展哪些宏?”这可能会给我一些线索,让我知道下一步该怎么做。

更多背景:我正在尝试在 Beamer 中使用 json 对象的算法列表。

我的标题中有以下内容定义:

\usepackage{algorithmicx}
\usepackage{algorithm}
\floatname{algorithm}{Example}

    {\}}{{{\color{delim}{\}}}}}{1}
    {[}{{{\color{delim}{[}}}}{1}
    {]}{{{\color{delim}{]}}}}{1},
}

Beamer 文件中框架的代码是:

\begin{frame}{Proc4 Messages}
  \begin{columns}
    \begin{column}{0.5\textwidth}
      \begin{algorithm}
    \begin{lstlisting}[language=json]
      {
        app:"ecd://coe.fsu.edu/EPLS/AssessmentName",
        uid:"Student/User ID",
        timestamp:"Time at which event occurred",
        verb:"Action Keyword",
        object:"Object Keyword",
        data:{
          field1:"Value",
          field2:["list","of","values"],
          field3:{part1:"complex",part2:"object"}
        }
      }
  \end{lstlisting}
      \end{algorithm}
    \end{column}
    \begin{column}{0.5\textwidth}
      \begin{itemize}
       \item Application header defines vocabulary used in other
          fields.
       \item ...
        \item Data field can hold any number/kind of object.
      \end{itemize}
    \end{column}
  \end{columns}
\end{frame}

相同的列表在另一个使用 article 而不是 beamer 样式的文档中运行良好,并且框架的其余部分非常标准。

事实证明,这与在 https://stackoverflow.com/questions/2981008/latex-issue-with-beamer-and-listings

如果我改变\begin{frame}{title...}它,\begin{frame}[containsverbatim]{title...}它就会按预期工作。
