Grafana variables

Hey, I am pretty new to Grafana, so I might not know much, but I am facing some issues with global variables in Grafana:

  • when I add variables and configure it to my pannels , it works well but the next day i tried again and all my data fails to register for some reason why is that ??

but if i remove the query , it works :

Also my variable are showing empty until i manually save my variable again :

i have to deselect and select the include all option for it to work :

Also my query are of type :
{
“find”: “terms”,
“field”: “Graphics.keyword”,
“query”: “*”,
“size”: 10
}
