I’m working on getting Twilio app-to-phone voice calls working.

Here’s my current flow.

• Client clicks the “Make Call” button on my website.
• My site sets up the Twilio device and calls const call = await twilioDevice.connect({ params });
• On my server, the endpoint specified in Twilio App-> Voice Configuration ->Request URL is hit. This endpoint is called “/make-calls” (This all seems to work as expected up to this point).
• My “make-calls” endpoint calls twilioClient.calls.create() and returns this xml to Twilio:

    <?xml version="1.0" encoding="UTF-8"?><Response>
        <Connect>true</Connect>
        <Play>true</Play>
    </Response>

• I get a Twilio error saying: “”XML Validation warning”,”line”:”2″,”parserMessage”:” Element ‘Connect’ cannot have character [children]”,”ErrorCode”:”12200″”

Questions:

• How can I correct this xml?

• Is it okay to have twilioClient.calls.create() in that endpoint, or is it supposed to be somewhere else?

  Here’s the code from my “make-calls” endpoint:

    console.log('-----')
    console.log('/make-calls. req?.body:', req?.body);
  
    let nurseId = req?.body?.nurseId;
    const navData = await getNavigatorData(nurseId);
    const toNumber = navData?.phone_1;
    let nurseName = navData?.name_first;
    const twilioPhoneNumber = Meteor.settings.private.twilio.phoneNumber;
    console.log('toNumber:', toNumber);
  
    let xml = '';
    const twilioClient = twilio(accountSid, authToken);
    try {
        const call = await twilioClient.calls.create({
            url: `${baseUrl}twiml`,
            to: toNumber,
            from: twilioPhoneNumber,
            // twiml: twimlString,
            machineDetection: 'Enable',
            AsyncAmdStatusCallback: `${baseUrl}handle-amd-result`,
            statusCallbackEvent: ['initiated', 'ringing', 'answered', 'completed'],
            statusCallbackMethod: 'POST',
            machineDetectionTimeout: 30
        })
  
        let responseObject = {
            Response: {
                Connect: true,
                Play: true
            }
        }
        xml = "<?xml version="1.0" encoding="UTF-8"?>" + xmlJs.js2xml(responseObject, xmlJsOptions);
        console.log('xml: ', xml)
        res.set('Content-Type', 'text/xml');
        res.status(200).send(xml);
    } catch (err) {
        let responseObject = {
            Response: {
                Success: false,
                Message: 'Failed to initiate call',
                Error: err.message
            }
        }
        xml = "<?xml version="1.0" encoding="UTF-8"?>" + xmlJs.js2xml(responseObject, xmlJsOptions);
        res.set('Content-Type', 'text/xml');
        res.status(500).send(xml);
    }
