Hi !

ES Version - 8.10.2  
Kibana version - 8.10.2

So i have written a plugin to add to kibana. and i did this in kibana 8.10.2 dev only.

it works perfectly in my wsl (my dev env).  
when i use "yarn build" and use it, my kibana setup on my windows doesnt open and i get

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

and checking the console log

```auto
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+yeZuJXiOi/3fqhGsU7BE='), or a nonce ('nonce-...') is required to enable inline execution.

bootstrap.js:42 ^ A single error about an inline script not firing due to content security policy is expected!
:5601/66404/bundles/plugin/visevent/1.0.0/visevent.plugin.js:1 
        
        
        Failed to load resource: net::ERR_CONTENT_DECODING_FAILED

```

checking online for solutions on the net and forum, i have set csp.strict to false in my kibana.yml

```auto
server.port: 5601
server.host: "0.0.0.0"
elasticsearch.hosts: ["http://localhost:9200"]
elasticsearch.username: "kibana_system"
elasticsearch.password: "w2i7j*UcSYHialiJCeV9"
csp.strict: false

```

i also read on one of the issues in the kibana git talking abt openssl legacy support.

this is my package.json file

```auto
  "name": "visevent",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "bootstrap": "yarn kbn bootstrap && yarn install",
    "build": "NODE_OPTONS=--openssl-legacy-provider yarn plugin-helpers build",
    "dev": "node --openssl-legacy-provider ../../scripts/plugin_helpers dev",
    "plugin-helpers": "node ../../scripts/plugin_helpers",
    "kbn": "node ../../scripts/kbn"
  },
  "dependencies": {
    "html2canvas": "^1.4.1",
    "vis-data": "^7.1.7",
    "vis-network": "^9.1.9"
  }
}

```

this is a project i am doing. not a proper official production or so.  
so i dont really care for security as long as it works and i can take screenshots to include in my report.

When i remove the plugin and start es and kibana, it works. so i know the problem is when the plugin comes into the picture.

Kindly requesting some help! Thanks in advance

Hi Srinivasa,

For solving the error = Error: error:0308010C:digital envelope routines::unsupported

You just have to add "export NODE\_OPTIONS=--openssl-legacy-provider &&" to plugin-helpers script  
Like this:

```auto
{
  "name": "test",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "bootstrap": "yarn kbn bootstrap && yarn install",
    "build": "yarn plugin-helpers build",
    "dev": "yarn plugin-helpers dev",
    "plugin-helpers": "export NODE_OPTIONS=--openssl-legacy-provider && node ../../scripts/plugin_helpers",
    "kbn": "node ../../scripts/kbn"
  }
}

```

If your plugin has a UI then you have to open a separate terminal , navigate to the root of plugin.  
and run

```auto
yarn dev --watch

```

Keep this terminal open.

And on new terminal run:

```auto
yarn start --run-examples

```

Let me know if you are still facing the same issue.

Hi @Sanskar_Panchal

Thank you so much for your response. I actually got everything working.

I added the csp.rules allowing inline and the csp blocking issue got solved.

As for the decoding problem, i just deleted the "\<plugin\_name\>.br " files inside the plugin root\>target\>public folder  
and it started working
