Dancer2 0.204002 Redis session data lost on redirect

[ramkisuni]

Hi,
I have

• ubuntu 16.04 LTS server
• PERL v5.22.1
• Dancer2 0.204002
• Redis server v=3.0.6 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=687a2a319020fa42

When I use Memcached, session it is working fine. But when I installed Redis and setup Redis session engine in config.yml, session data is lost.

Config.yml:
engines:
session:
Redis:
cookie_name: sippat_localhost.session
cookie_duration: 86400
session_duration: 86400
redis_server:
127.0.0.1:6379

session: Redis

My redis-cli ping PONG works fine and able to see the same session ID both in the browser and redis-cli (KEYS *);

To redirect I use, redirect uri_for('/users/' . $user->id); but I keep getting back to sign-in page.

Tried understanding issue 811 but it seems older versions of Dancer2.

Being a noob to both Perl and Dancer2, hope I have not missed something important to do or report here.

ok, in my setup, though Redis serialization is given as optional, if I enable it, redirection works for me

-- In my carton cpanfile I have the following modules
requires "Sereal::Encoder";
requires "Sereal::Decoder";
requires "Dancer2::Session::Redis";
requires "Dancer2::Session::Redis::Serialization::Sereal";
-- so carton install installed these modules

my config.yml looks like
engines:
session:
Redis:
cookie_name: redis_users.session
cookie_duration: 86400
session_duration: 864000
is_secure: 0
is_http_only: 0
redis_server: 'localhost:6379'
redis_serialization:
module: "Dancer2::Session::Redis::Serialization::Sereal"
compression: "snappy"
