Ratel frontend breaks on cluster page after removal of Enterprise license in v25.0.0

[eileenaaa]

Hi Dgraph team,

After upgrading to v25.0.0, I noticed that the Enterprise license has been removed. The related PR is here: #9367, and the changes remove the License field from the getState response:
state.go diff.

Issue

When a user in the guardians group clicks the Cluster menu in Ratel, the page should display information about Zeros and Groups.
However, the frontend still attempts to access clusterState.license, which no longer exists in the API response.

This leads to a console error:

ClusterPage.js:125  Uncaught TypeError: Cannot read properties of undefined (reading 'expiryTs')
    at ClusterPage.js:125:46
    at of (ClusterPage.js:266:10)

As a result, the Cluster page fails to render.

Fix

I updated the frontend so that it:

• Uses optional chaining and nullish coalescing to safely read license-related data.
• Renders license/certificate information only when the license field exists.

This prevents runtime errors and allows the Cluster page to render correctly even when no license is present.
