what is fetchApis.dynamic ?

fetchApis.dynamic is just return fetch(localhost:3000/${path}?...) with types.

try removing headers: ...

It’s working…
but that’s just set Cookies. Why remove header working?…

what is inside await defaultHeaders() ?

in the server you call cookies() and that probably opts out of the data cache.

its weird since you probably dont want to cache requests that rely on user request

if you want to make the server request "cacheable" then use a pregenerated cookie instead of getting it from the user (via cookies())

then you can use the next.js backend to filter out anything if the user (for example) doesnt have permission

by caching in next.js that means you allow any request to be made in the server regardless of user permission, and handling auth checks in the next.js itself against the returned cached data

so you no longer rely your backend to do the auth checks

that is the pattern you'd use if you want to opt-in into data caching

the typeof window === 'undefined part is already a step in the right direction. i like that part

Okay i got it. I try change that.

@ᴉuɐpɹɐɐ Could I get an example code...?

which part?

How to use pregenerated cookies inside server?

here

just remove Cookie

you dont need it right?

If the cookie is removed, the data cache functions properly. But we need Cookies.

Client cookie have a authentication infos...

your client cookie will automatically be sent to the server using fetch()

its part of how cookies works

But sever side request not have cookies…
