javascript - SignalR upgrade 0.5.3 to 1.0.x issues -

i have/am upgraded/upgrading signalr 0.5.3 1.0.x rc2 , having problems creating connection.

the issue hitting exception:

typeerror: res null

connection.apprelativeurl = res.url;

my script create connection has been stripped right default demo code:

var connection = $.connection('/signalr'); connection.start(function () { console.log("connection started!"); });

still error. when step jquery.signalr.js file, , nail connection code:

var url = connection.url + "/negotiate"; connection.log("negotiating '" + url + "'."); $.ajax({ url: url, global: false, cache: false, type: "get", data: {}, datatype: connection.ajaxdatatype, error: function (error) { $(connection).triggerhandler(events.onerror, [error.responsetext]); deferred.reject("signalr: error during negotiation request: " + error.responsetext); // stop connection if negotiate failed connection.stop(); }, success: function (res) { var keepalivedata = connection.keepalivedata; connection.apprelativeurl = res.url;

i'm getting lastly line , res parameter null bombing out connection attempt. have updated signalr dependencies, changed hub client side calls utilize additional client/server properties in hubs.

my /signalr/hubs js script beingness created , has right methods mapping server side hub methods expect available. js file follows:

any ideas?

turns out there nil wrong code above. migration signalr 0.5.3 1.0.x went without hitch. problem dev environment quite messed up.

there 1 massive gotcha in our case - using ravendb. there dependency both on different versions of newtonsoft json.

if you're in situation using both of these technologies together, careful passing json objects formatted in previous version of newtonsoftjson 1 other resultant json serialized objects not backward compatible.

you have map them manually when passing raven signalr js client.
