Error parsing form: Error: missing content-type header

[InTheCloudDan]

I am trying to post to multi-party using default mailin configuration with Nodejs - v6.2.0

the /webhook is giving the error Error parsing form: Error: missing content-type header

I installed mailin using -g, I see where the mailin script itself is but not a configuration or module file where I could add more console.log commands to see how it it is being built
