`no kind "ExecCredential" is registered` when adding EKS cluster

[ravindraprasad85]

I am trying to add external cluster but its not getting added , My request and suggestion is to add the feature where we can add external clusters using UI or through helm charts (values.yaml)

Appreciate the consideration of this request

@ravindraprasad85 You can add clusters directly by creating a secret with the relevant information. See declarative setup https://argo-cd.readthedocs.io/en/stable/operator-manual/declarative-setup/#clusters

We won't add cluster creation to the UI because we need access to a kubeconfig to do it and the declarative option already works well for those that want to handle it manually.

Don't get me wrong, if you make a PR for it, maybe we could get it merged but I think not going to get any attention from maintainers. Closing issue, feel free to reopen if you think I missed something.

I'm using eks fargate 1.26 version and argocd version as 2.7.6. I'm receiving the same error.

argocd cluster add $CONTEXT_NAME

Is there anything I need to change with argocd version

Re-titling and re-opening to track the error message rather than the UI enhancement request.
