Greeting from China! I have one question regarding error message “” in SAP cloud platform where I would like to consume an OData service from SAP cloud for customer ( C4C system).

I have a nodejs application where I hard code an end point to an OData service in C4C system. The request is sent to C4C and then I display the result in nodejs console.

The end point for C4C OData service:

https://qxl.dev.sapbydesign.com/sap/byd/odata/v1/opportunity/OpportunityCollection(‘00163E06551B1EE79E9E69D7F8FBCDCF’)

When I test this application locally, it works perfect.

var sURL = "https://qxl-cust233.dev.sapbydesign.com/sap/byd/odata/v1/opportunity/OpportunityCollection('00163E06551B1EE79E9E69D7F8FBCDCF')";var username = 'WANGJER'var password = 'Saptest1'var options = {url: sURL,auth: {user: username,password: password},headers: {'Accept': 'application/json','Content-Type': 'application/json'}};request(options, function (error, response, body) {// console.log('body:', body); var opportunity = JSON.parse(body);var line1 = "Opportunity name: " + opportunity.d.results.Name;console.log(line1);var line2 = "Responsible: " + opportunity.d.results.MainEmployeeResponsiblePartyName;console.log(line2);var line3 = "Opportunity id: " + opportunity.d.results.ObjectID;console.log(line3);var responseText = line1 + "\n" + line2 + "\n" + line3;res.send(responseText);res.send("another line"); // this line will cause error - repeated send response is not allowed});

After I upload it to Cloudfoundry@SCP, it fails to work: I set breakpoint in C4C system and found that the request sent from SCP NEVER reaches C4C system. After some times, SCP received error message “502 Bad Gateway - Registered endpoint failed to handle the request”.
