Error clearing account from cookies:

Error message

Error clearing account from cookies: 

What it means

SignOutHandler reports HTTP 500 at app/server/handlers/sessions.go:276-281 when ClearAccountFromCookies returns an error while removing account-identifying cookies for auth.User.Id. Like the auth-cookie clear, this operates on response headers and fails when headers/body were already written or the helper errors internally.

Solutions

1. Check the logged 'Error clearing account from cookies: ...' text for http header-write errors
2. Verify the clear helper's cookie Name/Path/Domain exactly match those used when the cookie was set
3. Make sure nothing writes to w before this point in the request lifecycle
4. Treat as non-fatal: the server-side token is already deleted, so log and continue instead of returning 500

Example fix

// before
err = ClearAccountFromCookies(w, r, auth.User.Id)
if err != nil {
	http.Error(w, "Error clearing account from cookies: "+err.Error(), http.StatusInternalServerError)
	return
}
// after
err = ClearAccountFromCookies(w, r, auth.User.Id)
if err != nil {
	log.Printf("Error clearing account from cookies: %v\n", err) // non-fatal
}

// server-side: confirm cookie attributes match before clearing
const accountCookiePath = "/" // must equal the path used at Set time

func cookieExists(r *http.Request, name string) bool {
	_, err := r.Cookie(name)
	return err == nil
}

err := ClearAccountFromCookies(w, r, userID)
if err != nil {
	log.Printf("account cookie clear failed, falling back: %v", err)
	http.SetCookie(w, &http.Cookie{Name: "account", Value: "", Path: "/", MaxAge: -1})
}

When it happens

Trigger: Sign-out request where the account-cookie clearing helper fails: response already committed, malformed cookie attributes, or helper-internal failure computing the cookie value for the given user id.

Common situations: Header already sent by earlier middleware, cookie set with a path/domain that the clear call does not match, or cookie names changed in a release so the clear helper no longer matches what was set.
