can not use categories page

[Luosuu]

I add categories=["type"]in my front matter, it's in toml
it looks like:

+++
author= "luosuu"
title= "title"
date= 2019-11-12T10:30:46+08:00
discription=""
categoires=["notes"]
weight=1
tags=["some tags"]
toc=true
+++

but in categories page there is nothing.
I don't konw whether I should change something in congfig.toml or should add a html file somewhere.Thanks you
