Dredd Hangs When Using Body Parser and Editing Body in Hook

[smizell]

If you do the following steps, Dredd will hang when running.

1. Use body-parser with express.js.
2. Use a before hook
3. In the hook, change the body to some string
4. Run Dredd with that hook

I haven't tested out your sample to try to reproduce, I just wanted to note that any time you change the body you'll also need to update the content-length. Most servers don't like when they don't match.

before "My > API > Transaction", (transaction) ->
  body = JSON.parse transaction.request.body
  body.property = "something else"
  transaction.request.body = JSON.stringify body
  transaction.request.headers['Content-Length'] = transaction.request.body.length

A good feature request would be to automatically ensure that the content-length is in sync with the actual length of the content.
