Issue/Introduction

NSX Application Deployment(NAPP) fails with the error "Helm pull chart operation failed. Not able to access yaml from location: /config/vmware/napps/charts/nsxi-platform-advanced/Chart.yaml"

This can occur when the deployment is via Manual method (i.e., deploying it directly via NSX Manager) or also when deployment is attempted via an NAPP Automation Appliance.

 

Environment

NAPP >= 4.2

Cause

This is a timing error where the NSX manager tries to look for the chart before it actually is downloaded.

Resolution

To resolve this issue, 

1. Login to the CLI of all the NSX Managers in the cluster separately with root credentials.

2. Navigate to the location /config/vmware/napps/charts/

3. Remove the files and directories under it by executing rm -rf *

4. Retry the deployment by clicking on "Retry" option / "Update/Redeploy" option.
