I haven't experienced that error myself. I'll do my best to reproduce it and, if I do, figure out what to do. However, I'm traveling with limited available time so I can't confirm when I'll get to it.

@vfarcic when I try to log the crd I found similar type error. Would you please check.

Sorry for not responding earlier. I was (and still am) traveling with little to no free time. I'll do my best to double-check it soon.

@vfarcic Thanks for the Response, Enjoy the Trip

I follow the steps exactly, is there any reason that open http://$ARGO_WORKFLOWS_HOST render 502 bad gateway?

To avoid it, in argo-server ingress set the path to "/argo(/|$)(.*)", not as it is by design "/" (root directory). See https://argoproj.github.io/argo-workflows/argo-server/#ingress as reference.
