Hey all,

I have an app hosted on heroku that is trying to access Salesforce data layer.
I am trying to user Sfdc.canvas.client.ajax but im unable to get neither a SUCCESS or FAILURE from this call.
I also am not facing any error.

Please find my code below :

                        function doFunction(){
                            var sr = JSON.parse('<%=signedRequestJson%>');
                            alert(Object.values(sr));
                            alert(JSON.stringify(sr, undefined, 2));
                            alert(JSON.stringify(sr.client.oauthToken, undefined, 2));
                            console.debug('xaxa' + Object.values(sr));
                            console.log("XAXA" + Object.values(sr));
                            //var sizes = Sfdc.canvas.client.size();
                            //alert('CLIENT SIZE' + sizes);
                            var csId =sr.context.environment.parameters.contactid;
                            alert('csID' + csId);
                            //Creating a variable with query Structure
                            var queryUrl= sr.context.links.queryUrl+"?q=SELECT+id+from+Contact+where+id='"+csId+"'"; 
                            //var xaxaurl = sr.context.links.queryUrl+"?q=SELECT+ID,NAME+FROM+CASE";
                            alert('QUERYCALL' + queryUrl );
                            //alert('OOGA WOOGA  BOOGA' );
                            
                            // Below block makes an AJAX call to Salesforce
                            
                            Sfdc.canvas.client.ajax(queryUrl,
                            { client : sr.client, //Send the req to signed request Client which has the OAuth – The Same request that requested Post to TMG - reused
                                method: 'GET', // GET method will request the fetched record details back from Salesforce
                                contentType: "application/json",
                                token : sr.client.oauthToken,
                                success : function(data) {
                                    alert('SUCCESS');
                                    console.debug("SUCCESS");
                                    console.log("SUCCESS");
                                },
                                failure : function(error) {
                                    alert('FAILURE');
                                    console.debug("SUCCESS");
                                    console.log("SUCCESS");

                                }
                            });
                        }

Please let me know if theres anything wrong that i'm doing ? anything missing from my end ?

Also can anyone provide me a link with the latest SDK with all the JS libraries (THE SDK in Canvas framework on github doesnt have the libraries)
Any help is appreciated.

I am also seeing the following errors when I inspect browser :
