To Reproduce

Update nextjs to version > 13.4.12

Describe the Bug

In my project I'm using custom expressjs server which sets few middleware functions and some of them extending request object with new fields and these fields was accessible in getServerSideProps function via context.request[here_new_my_new_field]. This approach worked up to the version 13.4.12.

Expected Behavior

Custom fields should be accessible in request object and I should see GUID is wow-test-guid
