Describe the bug
I'm unable to create modules from the Helm chart for Argo Workflows. Trying a popular chart like Argo was a debugging step after seeing the same error from various charts in private repos.

To Reproduce
Steps to reproduce the behavior:

1. In CyclopsUI, go to 'Templates'
2. Click on 'Add template reference'
3. Enter the following:

Repository URL:  https://github.com/argoproj/argo-helm
Path:  charts/argo-workflows

4. Attempt to create a module from this template. See error.

Expected behavior
No errors. Template options displayed for Argo Workflows.

Screenshots
Resulting error:

TypeError: Cannot read properties of null (reading 'forEach')
Check if Cyclops backend is available on: http://cyclops-ctrl.cyclops:8080

Desktop (please complete the following information):

• OS: Windows 10
• Browser: Edge
• Version: 129.0.2792.79
• CyclopsUI version: v0.13.1
• Kubernetes distro: K3s installed with Rancher Desktop

Additional Context
On the bright side, the new private templates feature works as expected.
