Deployment to Heroku

Has anyone had success with using the docs at Blitz website for deployment to Heroku. I tried it twice today and I keep getting the terminal error:

remote:  ›   Error: Unexpected argument: --production

error: failed to push some refs to 'https://git.heroku.com/test-ah001.git'

I copied over the npm commands & created the Procfile as per the instructions, however, I don't know how --production flag error needs to be handled. Thought, I would ask here before raising an issue.

Oops! Sorry, it should be blitz build instead of blitz build --production.

I just fixed the docs
