No value given in filter when using valueText

[michaverhagen]

The query below comes back with an error when using valuetext. The problem goes away when you replace it with valueString

  Aggregate {
    Things {
      RetailLine (where: {
        path: ["market"]
        operator:Equal
        valueText: "Albert Heijn"
      }){
        unitSales {
          sum
        } 
      }
    }
  }
}```
