Why does saga not execute on the server side, but saga runs normally on the client side?

Describe the bug

Why does saga not execute on the server side, but saga runs normally on the client side?

The strange thing is that in my local development environment, when I run npm run dev for the first time, the saga does not work, but when I modify the jsx file and hot load it, the server-side saga works

But when I package it in the production environment, the server-side saga doesn’t work

It doesn’t seem to be working, here’s an example of when first launching it using the page for access. It does not execute the asynchronous function inside saga

https://codesandbox.io/s/jovial-night-mtkbt?file=/pages/index.js

Because the console.log of the asynchronous function is not printed

I hope you can help me to answer my questions, thank you very much!
