uPnp SetAVTransportURI Missing SOAP action header

Question

I am playing about with bubbleUpnp and looking at uPnp in general. I've put out a urn:schemas-upnp-org:device:MediaRenderer:1 discovery and the app notifies of its capabilities.

The first issue is I have xmbc on different devices, ps3, ps4 all can see each other but only the bubbleUpnp and my router replies ( that goes for ssdp:all to).

trying to get set a AVTransportURI on bubbleUpnp i keep getting a uPnp error

<s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <s:Fault>
            <faultcode>s:Client</faultcode>
            <faultstring>UPnPError</faultstring>
            <detail>
                <UPnPError xmlns="urn:schemas-upnp-org:control-1-0">
                    <errorCode>401</errorCode>
                    <errorDescription>No action by that name at this service. Missing SOAP action header.</errorDescription>
                </UPnPError>
            </detail>
        </s:Fault>
    </s:Body>
</s:Envelope>

But grabbing the header from charles shows its there.

POST
/dev/9bfe134f-b027-52f3-ffff-ffffaae644dd/svc/upnp-org/AVTransport/
action HTTP/1.1 Host    192.168.1.65:58645 Accept   */*
Accept-Encoding gzip, deflate Content-Length    429
Content-Type    text/xml; charset=utf-8 Accept-Language en-us
soapaction  urn:schemas-upnp-org:service:AVTransport:1#
SetAVTransportURI Connection    keep-alive
User-Agent  channelListingTest/1 CFNetwork/758.3.15 Darwin/15.4.0

heres the soap request

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <s:Body>
        <u:SetAVTransportURI xmlns:u="urn:schemas-upnp-org:service:AVTransport:1">
            <InstanceID>0</InstanceID>
            <CurrentURI>http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4</CurrentURI>
            <CurrentURIMetaData />
        </u:SetAVTransportURI>
    </s:Body>
</s:Envelope>

and under the soap tab in charles it looks ok to me

SetAVTransportURI   Method  
Parameters  Element 
[InstanceID: null]  Element 0
[CurrentURI: null]  Element http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4
[CurrentURIMetaData: null]  Element

It could be my in experience with soap/upnp does anything stick out ?

Cheers

edit heres the code to send the request.

                var request = new XMLHttpRequest();
                request.open("POST", "http://192.168.1.65:58645/dev/9bfe134f-b027-52f3-ffff-ffffaae644dd/svc/upnp-org/AVTransport/action");

                request.onreadystatechange = function() {
                        console.log(request.responseText)
                };

                let setAVTransport = '<?xml version="1.0" encoding="utf-8"?>' +
                                        '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">' +
                                                '<u:SetAVTransportURI xmlns:u="urn:schemas-upnp-org:service:AVTransport:1">' +
                                                    '<InstanceID>0</InstanceID>' +
                                                      '<CurrentURI>http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4</CurrentURI>' +
                                                    '<CurrentURIMetaData></CurrentURIMetaData>' +
                                                '</u:SetAVTransportURI>' +
                                            '</s:Body>' +
                                        '</s:Envelope>';

            request.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
            request.setRequestHeader("SOAPAction", "urn:schemas-upnp-org:service:AVTransport:1#SetAVTransportURI");

                request.send(setAVTransport);

Answer 1

I can't promise this is the real issue but the SOAPAction value should be in doublequotes (don't ask me, I don't think it makes any sense either).

Try something like this:

request.setRequestHeader("SOAPAction", "\"urn:schemas-upnp-org:service:AVTransport:1#SetAVTransportURI\"");

In general I advice to check the actual messages on the network (wireshark is a great tool) and compare them to messages sent by a client that does work.
