Graphql : AND operation

Questions and Answers

I want to query all my foodtrucks filter by reservations.location.id AND by reservations.schedule.scheduleDate

I’ve read this post : Strapi graphql OR operator for where clause - #5 by sethpkendall
And I try to do that :

//Variables
{
  "location": "60be40f06a15ab675c91f415", //Unil
  "date":"2021-08-18"
}

query FoodtrucksReservationsLocation($location: ID!, $date: String!) {
    foodtrucks(
      where:{ _where: 
        [{reservations:{ location:{id:$location}}}, {reservations:{schedule:{ scheduleDate:$date}}}]
      }    
    ) {
      id
    title
  
    reservations{
      id
      schedule {
        scheduleDate
      }
      location {
        title
        id
        
      }
    }
      
  } 
  }

This is my response :
