   Could you make a backporting PR for `branch-3.1` please, @ulysses-you ?
   ```scala
   scala> val emptyAgg = Map.empty[String, String]
   emptyAgg: scala.collection.immutable.Map[String,String] = Map()
   
   scala> spark.range(2).where("id > 2").agg(emptyAgg).limit(1).count
   res0: Long = 1
   
   scala> spark.version
   res1: String = 3.1.2
   ```
