Next.js - Getting Error [ERR_HTTP_HEADERS_SENT] about iron-session HOT 7 CLOSED

Just to add another possible solution, drove myself crazy for hours implementing all the solutions online to no avail, walked away came back and realized I left the await out of await res.session.save();

from iron-session.

Hey, this issue seems related to nextjs itself, there's a discussion RFC: Returning redirects from getServerSideProps / getStaticProps

from iron-session.

Hi there, could you create a GitHub repository where I could reproduce the issue? Could it be that there's someplace trying to save the session after you already replied to the user? Thanks!

Weirdly the example from this repository (ssr example I believe) is working well. I am only using static generation though, not ssr in my apps

@develanet or @humayunj if you can reproduce this issue and create a repository out of it, I can help

from iron-session.

I can confirm this error can be sometime happened when you redirect on SSR using res.setHeader(....)

Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

I don't think the problem is with next-iron-session but Next.js framework behavior itself...

@vvo Thanks for your response but I am going with a different approach on this one.
