We are trying to setup a DPS service for Azure Iot hub, we want to setup proxy for Provisioning through X509, In the Sample code : "register_x509.js"
We are using "var Transport = require('azure-iot-provisioning-device-mqtt').MqttWs;" library. In that, there is function call "setTransportOptions" and we sending our proxy agent as a permeant there :
`var transport = new Transport();
transport.setTransportOptions({webSocketAgent:new HttpsProxyAgent(process.env.HTTP_PROXY)})
var securityClient = new X509Security(registrationId, deviceCert);
var deviceClient = ProvisioningDeviceClient.create(
provisioningHost,
idScope,
transport,
securityClient
);
// Register the device. Do not force a re-registration.
deviceClient.register(function (err, result) {
if (err) {
console.log("error registering device: " + err);
} else {
console.log("registration succeeded");
console.log("assigned hub=" + result.assignedHub);
console.log("deviceId=" + result.deviceId);
}`
Connection it's not happening, the initial tunneling is not happening. We also saw in documentation that Azure SDK has a proxy filter which automatically take Proxy variable from environment, we tried that as well but still no connection. Can please suggest a way for this use case.
Error we received : UnhandledPromiseRejectionWarning: Error: socket hang up
