Using the latest version of Fuse Console Operator 7.11 and deploying a Fuse Console with the following CR:

apiVersion: hawt.io/v1alpha1

    branding: {}
    online:

The Fuse Console shows successfully the AMQ Brokers and allows connecting them. However, the Broker Diagram does not show anything:

No error messages in the Fuse Console pod or in the web browser.
