Custom route path not working with authentication

[Hari Prasath P]

I have created an anchor tag in first page,

<div><a target="_blank" href="/secondPAge">Redirect to secong page</div>

Also defined a new path in my routes file like this,

app.get('/firstPage', addon.authenticate(), function(req, res) {
 res.setHeader('Access-Control-Allow-Origin','*');
 res.render('firstPage', { title: "First Page" });
}); 

app.get('/secondPage', addon.authenticate(), function(req, res) {
 res.setHeader('Access-Control-Allow-Origin','*');
 res.render('secondPage', { title: "Second Page" });
}); 

When I remove addon.authenticate() the page gets redirected, else throws error - "Unauthorized: Could not find authentication data on request". Have added the page references in atlassian-connect.json as,

"modules": {
 "generalPages": [
 {
 "key": "myaddonkeyfirstpage",
 "location": "system.top.navigation.bar",
 "name": {
 "value": "FirstPage"
 },
 "url": "/firstPage",
 "conditions": [{
 "condition": "user_is_logged_in"
 }]
 },
 {
 "key": "myaddonkeysecondpage",
 "location": "none",
 "name": {
 "value": "SecondPage"
 },
 "url": "/secondPage",
 "conditions": [{
 "condition": "user_is_logged_in"
 }]
 }
 ]
 }

 Can I load page using link in anchor tag? Or how to redirect to another page from first page with authentication?
