Seems to be the same error as #115.

I've just ran into this issue and found:

The problem here is that https://github.com/gin-gonic/contrib/blob/master/sessions/sessions.go

The default key is set to github.com/gin-gonic/contrib/sessions where as https://github.com/gin-contrib/sessions/blob/v0.0.3/sessions.go it is set to github.com/gin-contrib/sessions

Wherever you're calling session := sessions.Default(c) you're importing "github.com/gin-gonic/contrib/sessions" instead of "github.com/gin-contrib/sessions"

EDIT:

After further investigation in order to fix this you must find all references to github.com/gin-contrib/sessions (If you're using gin-gonic) to github.com/gin-gonic/contrib/sessions and follow the example here: https://github.com/gin-gonic/contrib/tree/master/sessions

For example I was using the cookie store so I had to refactor

    store := cookie.NewStore([]byte(os.Getenv("SESSION_SECRET")))

to:

    store := sessions.NewCookieStore([]byte("SESSION_SECRET"))
