No post content in index.html

I have created a working Hugo site and tested it locally. This is my second Hugo site, so not a total noob, but no expert either... When I follow your directions for the Heroku buildpack and push, almost everything looks good, except post content (example: post/name/index.html) are blank files. I get a 200 response, so the file is there, but it is empty. Generating public locally gives complete post file contents.
Heroku site is here: https://ajj2.herokuapp.com
fyi I am using an auto deploy from github to heroku.

As a comparison, I pushed the public site to another Heroku app (faked it with a index.php redirect to index.html in static). See https://ajj3.herokuapp.com for what I was expecting to see in the ajj2 Heroku app.
