Numaflow CRDs (Pipeline, MonoVertex): cannot see resource information or actions

[joshuase96]

Checklist:

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

Describe the bug

When clicking on a resource of type Pipeline or MonoVertex (CRDs from Numaflow) you get a blank screen and a lua discovery script syntax error. Information is not presented for the resource because of this bug. The same goes when trying to use the ellipsis menu to e.g. delete or sync the resource; the bug prevents the menu from showing up.

To Reproduce

Click on a resource of type Pipeline or MonoVertex (Numaflow CRD)

Expected behavior

A window appears with information about the resource, logs etc.

This issue is very similar to #23886, which I can see there have been commits that address.

I am not sure if the fixes for ESO CRDs will also work for Numaflow CRDs.

Hey, just took a small look.
At minimum the code of the discovery just looks broken.
I can try to fix that and add tests for it in a bit🙂
