Bad request when uploading a file

I am using the Box API from within a C++ application using Qt. Using the Qt library (QNetworkAccessManager, QHttpMultiPart, etc...), I am able to sign in, authenticate, get file listing and file content. However I have hit a road block with trying to upload a new file. All I get from the server is "400 Bad request" with no other message. If anyone can spot my mistake, I would really appreciate it! I've checked that the parent ID is correct and valid.

Here is (an example of) the raw request that I am sending out (the auth token is not shown for security):

POST /api/2.0/files/content HTTP/1.1

Authorization: Bearer XXXXXXXXXXXXXXXXXX

Content-Type: multipart/form-data; boundary="boundary_.oOo._MTA5NjYzOTY0Ng==MTUxNzg3MTc2OA==OTEyNTYyMDYz"

I tried testing the same type of request using curl, and this is what the headers looked like for a successful request:

One thing I note is the absence of double-quotes around the boundary value in the Content-Type header — could you try removing them and see if that helps?

HI
I am facing the same problem, i was wondering if you found a solution?
Also how did you get the request sent from qt?
