using mutlipart format with api gateway proxy
<p>I'm moving an existing API to use aws lambdas, but need to keep the current version running so I'm setting up aws gateway to proxy the existing api.</p>

<p>We have one api route which is a file upload. The headers we set are <code>api-key</code> and <code>api-name</code> which are being passed properly by api gateway, but I'm getting an error that says <code>missing boundary header</code>. </p>

<p>However, the boundary header is part of the content-type <code>Content-type: multipart/form-data, boundary=AaB03x</code> so I don't think I can set that directly. I was hoping it would get passed through.</p>

<p>Any suggestions on routing a file upload proxy through aws api gateway?</p>
