Plugin generator generates a plugin that causes an error

Hi,

I am trying to create a plugin for the latest version of Kibana [8.6]. I have used the plugin generator for this purpose. Unfortunately, after generating the plug-in and starting the server, I see this error:

Elastic did not load properly. Check the server output for more information.

In the Chrome console, I see only this error:

Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-P5polb1UreUSOe5V/Pv7tc+yeZuJXi3fqhGsU7BE='), or a nonce ('nonce-...') is required to enable inline execution.

Has anyone encountered a similar error? How do you fix it?

Thanks,
Przemek

This problem will be solved once the following PR gets merged fix(NA): external plugins development flow with the new modern package plugins in place by mistic · Pull Request #153562 · elastic/kibana · GitHub

Thanks for reporting it.
