Hi,  
I use Kibana 8.12.1 and make kiban plugin using " [**kbn-plugin-generator**] . [[kibana/packages/kbn-plugin-generator at main · elastic/kibana · GitHub](https://github.com/elastic/kibana/tree/master/packages/kbn-plugin-generator) ]. Unfortunately, after generating the plug-in and starting with "yarn start", I see this error:  
[ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. connect ECONNREFUSED 127.0.0.1:9200

 ![error server](https://us1.discourse-cdn.com/elastic/original/3X/f/f/ff5780cd449bbc80e019af07b3849987eab9839a.jpeg)

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

Thanks,  
Tingting

Can you confirm you have a running Elasticsearch cluster? You can spin up one with the `yarn es` command? More details about running Elasticsearch in development here:

> **[Running Elasticsearch during development | Kibana Guide \[7.17\] | Elastic](https://www.elastic.co/guide/en/kibana/7.17/running-elasticsearch.html)**
