I've obtained this error after creating the visualization element according the following link [How to bring Jupyter Notebook visualizations to Kibana dashboards for data science | Elastic Blog](https://www.elastic.co/blog/how-to-jupyter-notebook-visualizations-kibana-dashboards-vega-data-science) . I've installed kibana through docker-compose and the version of kibana is 7.12.0. Maybe I need to delete all the saved object. How can I manage to that? I've seen on the documentation that I can use delete rest operation but I don't know the id of the saved object. I 've the code the built them so I can recreate them as new. Kibana service was up until I've inserted to the kibana serverice a lot of graph. I've tryed to add memory to the virutal machine and on kibana itself but nothing change. Below is the log of what happened. I've not found out anything on hte web. Someone can help? ```auto kibana | {"type":"log","@timestamp":"2021-05-28T07:47:15+00:00","tags":["info","plugins","taskManager"],"pid":6,"message":"TaskManager is identified by the Kibana UUID: 70b8c42e-5405-437c-998f-4aa640b5173b"} kibana | {"type":"log","@timestamp":"2021-05-28T07:47:17+00:00","tags":["warning","plugins","security","config"],"pid":6,"message":"Generating a random key for xpack.security.encryptionKey.

> [@LombardoAndrea195](#): > > `"Unable to revive connection: http://elasticsearch:9200/"` Your logs suggest the Elasticsearch instance you try to connect to is not available. Make sure your Elasticsearch cluster is up and healthy, then start Kibana. ---

I manage to resolve. The problem was that Kibana has too much saved object. ---

Sorry @flash1293 I've obtained again this error I don't know why. I've imported only 5 element from vega how is it possible? ---

I don't think this is related to Kibana, it looks more like an Elasticsearch problem. Check the logs and health of your Elasticsearch cluster. ---

Yes you have right it's change the error as the problem of the elasticsearch. Could be that I need to insert a new node? Because I've only a node of elastic and one of kibana, maybe I need a cluster of node > ``` > kibana | FATAL Error: Unable to complete saved object migrations for the [.kibana] index. Please check the health of your Elasticsearch cluster and try again. Error: [undefined]: Response Error > kibana | > > ``` ---
