When the page changes, express doesn't work, getServerSideProps works.

Hi first,

I will explain my problem through an example.

I have a three components under the /pages.
/a and /b and /index
Example a :
class A extends React.Component(...render...) export async function getServerSideProps(ctx){ console.log("ServerSideProps running") }

Im using nextjs's Custom Server. (More information : https://nextjs.org/docs/advanced-features/custom-server)

example my server :
server.get("/a", async(req,res) => { console.log("Server side express running"); app.render(req,res,"/a",req.query); })

OUTPUT :
Server side express running,
ServerSideProps running

---

So far, no problem. But if I come back to page "b" after rendering a, then back to "a" page, the output looks like this:

OUTPUT:
Server side express running.
ServerSideProps running
// page changed /b and redirect again /a
ServerSideProps running

Is it a bug or my fault?

@phibersoft What are you expecting the output to look like?

[phibersoft]

Expected Output

Server side express running // path a
ServerSide props running // path a
// Page changed with next/link (/a to /b)
Server side express running // path b
ServerSide props running // path b
// Page changed with next/link (/b to /a)
Server side express running // path a
ServerSide props running // path a

Received Output

Server side express running // path a
ServerSide props running // path a
// Page changed with next/link (/a to /b)
ServerSide props running // path b
// Page changed with next/link (/b to /a)
ServerSide props running // path a
