All-in-one docker compose

Been playing around with adding identities from a couple of LXC servers (hosting different things) in my local Proxmox using this method to install the edge-tunnel. It appears the /dev/net/tun device can't be shared by more than 1 LXC at the sametime. So I was planning on enrolling the edge-tunnel on just one LXC and use that to proxy to other servers in my network. But it looks like I'm running into the same issue as this post here only my version combinations are different than his.
My ziti-edge-tunnel version is ziti-edge-tunnel version v1.2.2
My in zac, my versions displayed are: Controller: v1.1.15 ZAC: 3.4.3
I'm getting the same error as the other gentleman when I start the ziti-edge-tunnel.service with a fresh jwt file in the /opt/openziti/etc/identity/ folder:

INFO ziti-sdk:utils.c:167 ziti_log_init() Ziti C SDK version 1.1.2 

INFO: enrolled home-proxy.jwt in /opt/openziti/etc/identities/home-proxy.json

WARN ziti-sdk:model_support.c:202 model_parse() json parse error: expected comment
ERROR ziti-sdk:channel.c:943 on_tls_connect() ch[0] failed to connect to ER[quickstart-router] 

Do you have any suggestions on how to resolve issue?
