Products

• VMware Tanzu Application Service for VMs

Issue/Introduction

When you access Ops Manage Endpoints such as:

• Certificate endpoint - /api/v0/deployed/certificates?expires_within=3m
• Support bundle endpoint - /api/v0/support_bundle

The following error is thrown:

{"errors":{"base":["undefined method `cert_pem' for nil:NilClass"]}} 

Environment

Product Version: 2.10

Resolution

This error usually occurs in one following scenarios:

• A brand-new Ops Manager is used, but the user hasn’t deployed the BOSH Director.
• You recently used the API endpoint to regenerate leaf certificates, but haven’t done an Apply Changes.

In either case, to the fix this issue, do an Apply Changes on at least the BOSH Director.

Try accessing Ops Man endpoints again after the Apply Changes completes.
