Argo Workflows UI v3.7.7: the GRAPH in Cron Workflows view shows "Cannot read properties of undefined (reading 'forEach')"

[ncs-coder-ops]

Pre-requisites

• I have double-checked my configuration
• I have tested with the :latest image tag (i.e. quay.io/argoproj/workflow-controller:latest) and can confirm the issue still exists on :latest. If not, I have explained why, in detail, in my description below.
• I have searched existing issues and could not find a match for this bug
• I'd like to contribute the fix myself (see contributing guide)

What happened? What did you expect to happen?

I upgraded from v3.6.4 to v3.7.7 and noticed the addition of the GRAPH menu in the CronWorkflow view in the Argo Workflows UI. When I click on it I get the following output:

Cannot read properties of undefined (reading 'forEach')
 [Reload this page](javascript:document.location.reload();) to try again.

The browser back button doesn't work, so to move away from here I need to click for example on the WorkflowTemplates icon on the left and then click the browser refresh button.

This UI issue is noticed on both Edge and Chrome browsers it seems to be happening for Cron Workflows which have longer names: like I tested up to 18 chars which is ok but like 41 chars names exhibit the error.

Version(s)

v3.7.7

Paste a minimal workflow that reproduces the issue. We must be able to run the workflow; don't enter a workflow that uses private images.

Navigate to the Argo Workflows UI -> Cron Workflows ( on the left ) -> Select a Cron Workflow from the list and click on it -> GRAPH

Logs from the workflow controller

kubectl logs -n argo deploy/workflow-controller | grep ${workflow}

I don't see any errors in these logs related to the Cron Workflow that shows the error.

Logs from in your workflow's wait container

kubectl logs -n argo -c wait -l workflows.argoproj.io/workflow=${workflow},workflow.argoproj.io/phase!=Succeeded

The Workflow has succeeded as I can see it in the Workflows view.

Pretty sure this is still relevant. Doesn't work for me on 4.0.1
