I try to use ChartCard in dashboard but i get this error: "...count(): Argument #1 ($value) must be of type Countable|array,..."
I use ChartCard with KWidget in dashboard (my class X extends KWidget) and probably this piece of code is wrong: $this->use(\koolreport\amazing\ChartCard::class)
->settings(array(
"dataSource"=>MYDB::table("orders"),
...
Can you help me?
