Incorrect behavior when using default values for arguments

[shafreenAnfar]

Consider the below program,

service /graphql on new graphql:Listener(9000) {
    resource function get allLifts(string status = "OPEN") returns Lift {
        TLift[] tLifts = from var l in liftTable where l.status == "OPEN" select l;
        return new Lift(tLifts[0]);  
    }
}

Results in below error

{
  "errors": [
    {
      "message": "Syntax Error: Cannot parse the unexpected character \".\".",
      "locations": [
        {
          "line": 7,
          "column": 9
        }
      ]
    }
  ]
}

For the query

{
  allLifts {
    name
    id
    trailAccess {
      name
    }
  }
}

Expected

{
  "data": {
    "allLifts": {
      "name": "Lift1",
      "id": "l1",
      "trailAccess": {
        "name": "tail1"
      }
    }
  }
}

Attached the complete program as well.
