Heroku运行二进制版本的Web(golang)

I'm trying to use https://github.com/ryandotsmith/null-buildpack and have compiled web process version(linux x64) but when i'm doing git push heroku master process hangs on

remote: Compressing source files... done. remote: Building source: remote: remote: Build stream timed out, reverting to polling...............

Procfile:

web: /app/bin/www

Was caused by a heroku issue, resolved now https://status.heroku.com/
