REST Upload to Skydrive without Content-Length - rest

Question

I'm trying to upload a file to Skydrive where I don't a-priori know the Content-Length. With other storage services I can do this with chunked HTTP upload, but Skydrive always complains about Content-Length being invalid.
Here are the full headers I'm sending:
PUT /v5.0/me/skydrive/files/skydrive_test.js?overwrite=ChooseNewName HTTP/1.1
Authorization: Bearer <TOKEN_REDACTED>
host: apis.live.net
content-type: application/javascript
Connection: keep-alive
Transfer-Encoding: chunked
Here's the response I get back:
cache-control: private, no-cache, no-store, must-revalidate
transfer-encoding: chunked
content-type: application/json; charset=UTF-8
server: Live-API/16.4.1731.327 Microsoft-HTTPAPI/2.0
x-content-type-options: nosniff
x-http-live-request-id: API.c6afda25-2d9f-4248-9f49-001ccb3a9007
x-http-live-server: BAYMSG1010836
date: Wed, 15 May 2013 14:33:00 GMT
{ "error": { "code": "request_invalid_content_length",
"message": "The value for the Content-Length header isn't valid." }}
Is there any way I can do this without setting Content-Length (i.e. using chunked encoding)?
I'm using node.js to do this, but it should apply equally with any language using the REST API, hence I haven't tagged this with a particular language.
For example Dropbox offers the Chunked Upload command: https://www.dropbox.com/developers/core/docs#chunked-upload
And Google Drive, even though it says it wants Content-Length, doesn't need it for it's resumable upload API: https://developers.google.com/drive/manage-uploads#resumable
Is there an API I'm missing?
Edit: Things I've tried: Setting Content-Length: 0 results in it working, but the file is zero bytes. Setting Content-length:0 and Transfer-Encoding: chunked, results in the original error above.

Try setting a dummy content-length to see if it is acceptable. Otherwise set the file size.
If you are using node.js you can get the file size you are trying to upload and set the size to content-length in OCTETs. You can get the file size requiring the fs (filesystem) module in node.
var fs = require('fs');
fs.watchFile('some.file', function () {
fs.stat('some.file', function (err, stats) {
console.log(stats.size);
});
});
