Hi Folks,
Not sure if anyone had same problem but when deploying the ghcr.io/beamops/kanban:infrastructure-page image in the section Trigger Your Application to Autoscale Using a Prepared Stats Page the image the docker image is failing always with the following message:
10:43:34.149 line=1373 pid=<0.2390.0> registered_name=Kanban.InfrastructureMonitor file=gen_server.erl domain=otp mfa=:gen_server.error_info/8 [error] GenServer Kanban.InfrastructureMonitor terminating

I checked the autoscale name, it is definitely named swarm-asg not sure what could be happening.
The only thing different from the book is that I am using ap-southeast-2 as region.
