Saved Dashboard is missing id(key)

Hi,
I am trying to create a logs dashboard for postgresql, when i click on check data a pop shows "Data successfully recieved for the module " after that when i click for create dashboard it fails with errror "saved Dashboard missing"

Elastic search Version: 6.8.0
Can anyone help ??

Did you receive any errors in the terminal when you ran ./filebeat setup? It sounds like the Filebeat was not able to import the dashboards into kibana successfully.

I recieved error with http_proxy and when i unset the proxy it is working fine.

After unsetting the proxy you're still unable to load the dashboards though?
