Pivot kibana plugin installation: EACCESS permission denied

Hi Vera,
Thanks for your quick reply. Our Kibana is installed in Kubernetes using the official Elastic Kibana image, it seems is a CentOS Linux release 7.6.1810 (Core).
There is no sudo neither but finally we installed your plugin with a new Dockerfile based on the image from Elastic, changing user to root and then executing kibana-plugin.
We have reconfigured ES and Kibana to enable cors but still cannot see the pivot table in Kibana. Is there any other way than going to Kibana's UI to check if your plugin is correctly installed?
Thanks in advance.

This seems the problem:
{"type":"log","@timestamp":"2019-12-19T15:27:40Z","tags":["plugin","warning"],"pid":8,"path":"/usr/share/kibana/plugins/flexmonster_pivot","message":"Skipping non-plugin directory at /usr/share/kibana/plugins/flexmonster_pivot"}
If it is of any help.
Regards,
Alberto.

Corrected changing the user and permissions of the folder:

RUN chown -R kibana.kibana /usr/share/kibana/plugins \
 && chmod -R 755 /usr/share/kibana/plugins

Next problem, Kibana image does not include yarn and we get an error in the optimization phase:
FATAL Error: Optimizations failure.
7119 modules
ERROR in ./plugins/flexmonster_pivot/public/components/flexmonster/FlexmonsterPivotTable.js
Module not found: Error: Can't resolve 'flexmonster/flexmonster.min.css' in '/usr/share/kibana/plugins/flexmonster_pivot/public/components/flexmonster'

Module not found: Error: Can't resolve 'react-flexmonster' in '/usr/share/kibana/plugins/flexmonster_pivot/public/components/flexmonster'
 
We are not sure this is going somewhere. Too much work to install this plugin.

Alberto.

Hi Vera,
We had to unzip the file and copy everything inside a /kibana folder to be able to install it.
Now it is working and we can test your plugin, thank you very much!!!!

 Hi Vera,
 We can see now your plugin in Kibana but we cannot select any index (see attached).
 CORS is configured in Kibana and in Elasticsearch (at least is in the configuration files).
 Do the indices in ES need an special mapping? special naming? is your plugin expecting an specific field? We do not see any errors nor warnings in Kibana or ES logs.
 Regards,
 Alberto.
