Getting "No operation is in progress" when trying to Terminate sync

[teddy-wahle]

Checklist:

• [x] I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• [x] I've included steps to reproduce the bug.
• [x] I've pasted the output of argocd version.

Describe the bug

The UI and the API say a sync is happening:

But when I try terminate, it gives me this error

Unable to terminate operation: Unable to terminate operation. No operation is in progress

This is happening across all our clusters. I see nothing in the logs

To Reproduce

All I do is try to Terminate a running sync. Same error through CI and UI.

I tried re-creating the app. I've tried deleting application controller pods. It doesn't help.

Expected behavior

I expect the sync get terminated

Screenshots

Can you provide the pod logs for server and application controller pods after reproducing the issue?

[teddy-wahle]

@jgwest Here are logs from the two application controller pods and the two server pods. To create these logs I deleted all server and app controller pods so that all the logs were fresh. Then I went to UI and tried to terminate a sync in an app called vconductor and got the same error:

argocd-application-controller-1.txt argocd-application-controller-0.txt

argocd-server-55464bc74-zmhvr.txt argocd-server-55464bc74-jw67s.txt

You can see this in the logs:

time="2024-02-12T18:02:33Z" level=info msg="finished unary call with code InvalidArgument" error="rpc error: code = InvalidArgument desc = Unable to terminate operation. No operation is in progress" grpc.code=InvalidArgument grpc.method=TerminateOperation grpc.service=application.ApplicationService grpc.start_time="2024-02-12T18:02:33Z" grpc.time_ms=8.452 span.kind=server system=grpc

This might be because of sharding functionality which is known issue in 2.10.0 version.

PR is raised for this. https://github.com/argoproj/argo-cd/issues/17124

[morawat]

we are on 2.10.5 and still facing this issue.

I'm seeing this behaviour on v2.10.9+c071af8 too
