Hi,

I would like to use val© in upsert mutatation, but it returns error:

{
  "name": "t",
  "url": "https://XYZ.eu-central-1.aws.cloud.dgraph.io/mutate?commitNow=true",
  "errors": [
    {
      "message": "while lexing uid(this) <Device.structuralSim> uid(other) (t=val(c))  . at line 1 column 53: Invalid input: ) at lexText",
      "extensions": {
        "code": "ErrorInvalidRequest"
      }
    }
  ]
}

usert query looks like:

upsert {
  query{

    THIS as var(func: eq(Device.id,"Dev1"))
    
    var(func: uid(THIS)) {
      this as uid
      Q as all: count(Device.additionalProperties)
      P as math(1)
      THIS_PROPERTIES as Device.additionalProperties {
        THIS_ATT as Property.attribute
        OTHER as Property.devices @filter(NOT uid(THIS)) {
          ALL_PROPERTIES as math(Q/P)
        }
      }
    }

    var(func: uid(OTHER)) {
      SAME_VALUE as same: Device.additionalProperties @filter(uid(THIS_PROPERTIES))
      ONLY_ATT as only_att: Device.additionalProperties @filter(NOT uid(THIS_PROPERTIES)) @cascade {
        Property.id
        Property.attribute @filter(uid(THIS_ATT)){
          Attribute.inProperties @filter(NOT uid(SAME_VALUE))
        }
      }
    }

    var(func: uid(OTHER)) {
     SAME_VALUE_COUNT as c: count(Device.additionalProperties @filter(uid(SAME_VALUE)))
     ONLY_ATT_COUNT as a: count(Device.additionalProperties @filter(uid(ONLY_ATT)))
    }

    structural_sim(func: uid(OTHER)) @normalize {
     other as uid
     id: Device.id
     all: math(ALL_PROPERTIES)
     same_values: math(SAME_VALUE_COUNT)
     only_same_attributes: math(ONLY_ATT_COUNT)
     c as coefficient: math((SAME_VALUE_COUNT*1.0 / ALL_PROPERTIES*1.0) + (ONLY_ATT_COUNT*1.0 / ALL_PROPERTIES)*0.7)
    }
  }

  mutation {
    set {
      uid(this) <Device.structuralSim> uid(other) (t=val(c))  .
    }
  }
}

Upsert is working if I change (t=val(c)) to (t=1)

I run Dgraph instance on cloud. Version is v20.11.2-rc1-16-g4d041a3a

Variables on Facets aren’t supported. There is an open ticket for this.
