The Adoption Insights plugin in earlier versions of RHDH1.7 was disabled by default and required some actions (described here) to enable it. However, from version RHDH1.7 this plugin is enabled by default and upgrading to that version requires some actions to complete it successfully, otherwise you will get the following error:
/opt/app-root/src/node_modules/@backstage/backend-app-api/dist/wiring/BackendInitializer.cjs.js:196 throw new Error(`Plugin '${r.pluginId}' is already registered`); ^Error: Plugin 'adoption-insights' is already registered at #doStart (/opt/app-root/src/node_modules/@backstage/backend-app-api/dist/wiring/BackendInitializer.cjs.js:196:19) at process.processTicksAndRejections (node:internal/process/task_queues:105:5) at async BackendInitializer.start (/opt/app-root/src/node_modules/@backstage/backend-app-api/dist/wiring/BackendInitializer.cjs.js:163:5) at async BackstageBackend.start (/opt/app-root/src/node_modules/@backstage/backend-app-api/dist/wiring/BackstageBackend.cjs.js:19:5)Node.js v22.16.0
It is because there is a conflict with the previous definition of the Adoption Insights plugins, and the new ones enabled by default.
If your dynamic plugin configuration is similar to:
kind: ConfigMap apiVersion: v1 metadata: name: dynamic-plugins-rhdh data: dynamic-plugins.yaml: | includes: - dynamic-plugins.default.yaml plugins: # Other Plugins # Adoptions Insights - package: ./dynamic-plugins/dist/backstage-community-plugin-analytics-provider-segment disabled: true - package: oci://ghcr.io/redhat-developer/rhdh-plugin-export-overlays/red-hat-developer-hub-backstage-plugin-adoption-insights:bs_1.35.1__0.0.2!red-hat-developer-hub-backstage-plugin-adoption-insights disabled: false pluginConfig: dynamicPlugins: frontend: red-hat-developer-hub.backstage-plugin-adoption-insights: appIcons: - name: adoptionInsightsIcon importName: AdoptionInsightsIcon dynamicRoutes: - path: /adoption-insights importName: AdoptionInsightsPage menuItem: icon: adoptionInsightsIcon text: Adoption Insights menuItems: adoption-insights: parent: admin icon: adoptionInsightsIcon - package: oci://ghcr.io/redhat-developer/rhdh-plugin-export-overlays/red-hat-developer-hub-backstage-plugin-adoption-insights-backend:bs_1.35.1__0.0.2!red-hat-developer-hub-backstage-plugin-adoption-insights-backend disabled: false - package: oci://ghcr.io/redhat-developer/rhdh-plugin-export-overlays/red-hat-developer-hub-backstage-plugin-analytics-module-adoption-insights:bs_1.35.1__0.0.2!red-hat-developer-hub-backstage-plugin-analytics-module-adoption-insights disabled: false pluginConfig: dynamicPlugins: frontend: red-hat-developer-hub.backstage-plugin-analytics-module-adoption-insights: apiFactories: - importName: AdoptionInsightsAnalyticsApiFactory
Commented those references is required to avoid this issue.
This step should be described somewhere in the upgrading or Adoption Insights documentation as part of the upgrade from previous versions.
There are no Sub-Tasks for this issue.
