mkapi fails for me after fresh install

[justdanyul]

Steps to pre-produce

• mkdir test-mkapi
• cd test-mkapi
• python3.7 -m venv .env
• source .env/bin/activate
• pip install mkdocs
• pip install mkapi
• mkdocs new .

edit mkdocs.yml to look like

site_name: My Docs
plugins:
  - search
  - mkapi

Then issue mkdocs serve

Expected behavior:

Mkdocs will serve the default mkdocs website on 127.0.0.1:8000

Actual behavior

  <snip>
  File "/home/daniel/Repositories/binance-asyncio/.env/lib/python3.9/site-packages/mkapi/plugins/api.py", line 19, in create_nav
    for page in nav:
TypeError: 'NoneType' object is not iterable

Note

If i change mkdocs.yml to

site_name: My Docs
plugins:
  - search

all is good. generates, Mkdocs will serve the default mkdocs website on 127.0.0.1:8000 as expected

Additional information, poking around with it a bit showed that if I change my mkdocs.yml file to

site_name: My Docs
plugins:
  - search
  - mkapi
nav:
  - index.md

everything works.
