Cannot convert undefined to null to object

I'm getting this error Cannot convert undefined to null to object

it seems to fail in this line

entries(definitions['process.env']).forEach(writeDefs);

definitions['process.env'] is undefined

definitions has this value

{
'process.env.NODE_ENV': '"production"',
  'process.env.PORT': '3000',
  'process.env.VERBOSE': 'false',
  'process.env.HOST': '"localhost"',
}

I think i have figured out why this fails. Might be because of this jaredpalmer/razzle#611

I got it working by modifying the code to

  if (isHeroku) {
      delete definitions['process.env.PORT'];
      definitions['process.env.RAZZLE_PUBLIC_DIR'] = '"/app/build/public"';
    }

I'll try to submit a PR

seconded, I'm running into this issue myself and cannot get it running on heroku

Ahhh, I realized that I was getting this error because I was using this with Razzle 2 and this is not compatible yet. (i'm using razzle 2.2.0)

There is a PR that fixes this issue for me: Upgrade for compatibility with Razzle 2.

For now, I just pulled down mrwade's branch and that's working for me. Thanks @mrwade!
