Argocd CLI- "Failed to invoke grpc call"

[Wyifei]

Our company's certificate is terminated at F5 load balancer and F5 connect Nginx ingress controller via Http protocal.
The certificate include domain: argocd-cons.xxx.com

I've add --insecure in argo-server parameter as ingress set as below:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: argocd-server-ingress
namespace: argocd
annotations:
spec:
rules:

• host: argocd-cons.xxx.com
  http:
  paths:
  • path: /
    pathType: Prefix
    backend:
    service:
    name: argocd-server
    port:
    name: https

Currently, I could login argocd Web UI via https://argocd-cons.xxx.com, but when I try to use argocd CLI, system prompt:
WARN[0002] Failed to invoke grpc call. Use flag --grpc-web in grpc calls. To avoid this warning message, use flag --grpc-web

How could I avoid this warning message? By the way, we must terminate SSL in F5 according to our policy.

I'm suffering from this too D:

Same issue for myself.

Just redirect this warning to a blackhole if it bothers you, e.g. 2>/dev/null at the end of the command.

Is there a config setting or an environment variable or some such where we could set the --grpc-web flag to be true all the time?
This way, we wouldn't have to provide it for every argocd call from the command line.

Went spelunking through the code and found my way back to this.
tl;dr: export ARGOCD_OPTS="--grpc-web" in your shell.

Pass --grpc-web to argocd login. The config should persist in ~/.config/argocd/config. Tested, worked for me.
