Hi, I'm trying to use this plugin in X1011/X1011.github.io@cb87cf47ea7cba02a0195b37fb2f4ae870552629, but I get this error:

toc-and-anchor $ pug --obj pug-config.js experience.pug 

/home/dan/drive/programming/X1011.github.io/node_modules/pug-filters/lib/handle-filters.js:54

The offending line corresponds to this one in your source file, and it seems state.tokens.slice(-1) is empty when this occurs.

The same error occurred when i tried the other 2 toc plugins, markdown-it-toc and markdown-it-table-of-contents.
