Plugin startup fails in V7.9 but works in 7.3

pgervais · August 28, 2020, 5:45pm

My cbsa plugin fails on startup. It fails at xpackMainPlugin.registerFeature in init.js with the following message " FATAL Error: Feature cbsa specifies app entries which are not granted to any privileges: cbsa,kibana". I tried a number of combinations as shown in:

github.com

elastic/kibana/blob/a20469f038e04e3c5fb821ed0b38360fb9698fe2/docs/developer/architecture/security/feature-registration.asciidoc#example-1-canvas

== Plugin feature registration

If your plugin will be used with {kib}'s default distribution, then you have the ability to register the features that your plugin provides. Features are typically apps in {kib}; once registered, you can toggle them via Spaces, and secure them via Roles when security is enabled.

=== UI Capabilities

Registering features also gives your plugin access to “UI Capabilities”. These capabilities are boolean flags that you can use to conditionally render your interface, based on the current user's permissions. For example, you can  hide or disable a Save button if the current user is not authorized.

=== Registering a feature

Feature registration is controlled via the built-in `xpack_main` plugin. To register a feature, call `xpack_main`'s `registerFeature` function from your plugin's `init` function, and provide the appropriate details:

["source","javascript"]
-----------
init(server) {
  const xpackMainPlugin = server.plugins.xpack_main;
  xpackMainPlugin.registerFeature({
    // feature details here.
  });

What exactly is this error trying to tell me?
Why does it work in 7.3 and not in 7.9? (Checked the docs. Nothing obvious in Change Log).
My code is shown below. What changes are required?

      const xpackMainPlugin = server.plugins.xpack_main;
      if (xpackMainPlugin) {
        const featureId = 'cbsa';

        xpackMainPlugin.registerFeature({
          id: featureId,
          name: i18n.translate('cbsa.featureRegistry.featureName', {
            defaultMessage: 'cbsa',
          }),
          navLinkId: featureId,
          icon: 'questionInCircle',
          app: [featureId, 'kibana'],
          catalogue: [],
          privileges: {
            all: {
              api: [],
              savedObject: {
                all: [],
                read: [],
              },
              ui: ['show'],
            },
            read: {
              api: [],
              savedObject: {
                all: [],
                read: [],
              },
              ui: ['show'],
            },
          },
        });
      }

Kibana internals have changed a lot from 7.3 to 7.9. Plugins that work in 7.3 may not work in 7.9. Does cbsa plugin support 7.9?

Nathan,
I have used Eui Framework all the way through. From what i read , major changes will happen in 8.0. Given what i have provided, where is the best place to look?'m trying to get cbsa plugin to work under 7.9. Thats the point.

Try adding the line app: [featureId, 'kibana'],

below the line all: {

and

below the line read: {

Andrea,
Thanks for taking the time to respond. Well, one more step forward. Adding these line now allows the plugin to start up without the previous error message. However , when the plugin is invoked , it simplu loos. When i look at the console, i get the following error message:

*refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-P5polb1UreUSOe5V/Pv7tc+yeZuJXiOi/3fqhGsU7BE='), or a nonce ('nonce-...') is required to enable inline execution.

bootstrap.js:11 ^ A single error about an inline script not firing due to content security policy is expected!

So it pretty obvious that the ```
xpackMainPlugin.registerFeature({

needs to be setup properly. I'm running teh free or public domain version at this time. Will be getting licensed in the near future.

sorry for the late reply, you have to use plugins.features.registerFeature instead of server.plugins.xpack_main.registerFeature as written here https://github.com/elastic/kibana/blob/master/src/core/MIGRATION.md#plugin-services
