"argocd admin notifications template notify" fails when using "call .repo.getAppDetails" in the template

• 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

argocd admin notifications template notify throws an error when testing a notification that contains a call to .repo.getAppDetails.

To Reproduce

Setup this notification in the argocd-notifications configmap:

$ cat ./argocd-notifications.preprod-eu.yaml
[...]
template.app-sync-succeeded: |
message: |
  {{if eq .serviceType "slack"}}:check_ok:{{end}} Deployment <{{.context.argocdUrl}}applications/{{.app.metadata.name}}|{{.app.metadata.name}}> to `{{.context.environmentName}}-{{.context.region}}` environment succeeded!
  repository: `{{.app.spec.source.repoURL}}`
  {{if ne (index .app.metadata.annotations "release-values-prefix") nil }}
  tag: `{{ (call .repo.GetAppDetails).Helm.GetParameterValueByName (print (index .app.metadata.annotations "release-values-prefix") ".app.image.tag") }}`
  executor: `{{ (call .repo.GetAppDetails).Helm.GetParameterValueByName (print (index .app.metadata.annotations "release-values-prefix") ".release.lastAuthor") }}`
  {{end}}
[...]

Then call the CLI:

# Current kubecontext targets a live cluster and the 'argocd' namespace, which contains an ArgoCD 2.3.3 deployment
$ ./argocd-2.4.14 admin notifications --config-map ./argocd-notifications.preprod-eu.yaml template notify app-sync-succeeded myapp
failed to notify 'console:stdout': template: app-sync-succeeded:4:10: executing "app-sync-succeeded" at <call .repo.GetAppDetails>: error calling call: runtime error: invalid memory address or nil pointer dereference

Expected behavior

I would expect admin notifications template notify to succeed and return the templated text, with the CLI contacting the server to load dynamic data.

Version

ArgoCD server 2.3.3.
Reproduced with any client from 2.3.3 to 2.5.0-rc2.

Logs

Client doesn't log anything, didn't find anything related in server logs (I suspect this is entirely client side).

Additional data

• Removing the calls to .repo.GetAppDetails from the template fixes the calls, but of course prevents testing them.
• It does seem like the CLI contacts the server to load the app: passing a non-existent app name fails with the proper error applications.argoproj.io "myapp2" not found.

[hau21um]

call of repo function from "argocd admin notifications template notify" {{(call .repo.GetCommitMetadata .app.status.sync.revision).Author}} behaves the same.
version: v2.6.1+3f143c9

This is still failing in argocd: v2.12.4+27d1e64 with argocd-server: v2.10.5+335875d: failed to notify 'slack:xxx': template: app-deployed:2:48: executing "app-deployed" at <call .repo.GetCommitMetadata .app.status.sync.revision>: error calling call: runtime error: invalid memory address or nil pointer dereference
