Looks like an incompatibility between https://github.com/executablebooks/sphinx-external-toc/ and Sphinx.

I was working on my jupyter book this morning and I was able to build it. It is very strange now that I am getting this error. I have absolutely no idea how to fix it and I have to have my jupyter book submitted for an assignment on wednesday

@mccahim2 You might want to open this issue at https://github.com/executablebooks/jupyter-book/issues then, to get a faster response. This is unlikely to be a problem in Sphinx, although I might be mistaken.
