Error: Configuration Drift Details display indefinite loading spinner in VCF Operations 9.0.2

Products

• VCF Operations

Issue/Introduction

• Navigating to Fleet Management > Configuration Drifts shows drift detected.
• Clicking a vCenter to view drift details results in an indefinite "Loading..." spinner.
• The UI never finishes rendering the configuration differences.

Environment

VCF Operations 9.0.2

Cause

A logic error in the vc_profile.py script within the config-modules-docker container fails to correctly process the compliance URL variable, causing the front-end to hang.

Resolution

To resolve the loading hang in VCF Operations 9.0.2, apply the following script patch on the Cloud Proxy associated with the vCenter:

1. Log in to the Cloud Proxy via SSH.
2. Access the config-modules container:

    docker exec -it config-modules-docker sh 

3. Execute the patch command: 

    sed -i 's/context, merged_desired_values, VC_PROFILE_DOMAIN_CONFIGURATION_CHECK_COMPLIANCE_URL/context, desired_values, VC_PROFILE_DOMAIN_CONFIGURATION_CHECK_COMPLIANCE_URL/' /usr/lib/python3.11/site-packages/config_modules_vmware/controllers/vcenter/vc_profile.py

4. Exit the container and restart the service: 

    docker restart config-modules-docker 

5. Clear the browser cache and refresh the VCF Operations UI.
