Distance, polygon with Sparql - sparql

Question

In a project, I use big data which is in sparql.
I cannot calculate the distance and I cannot find all the files (PointofInterrest) that are in a point polygon (to display all the files that are in a region, for example).
I tried with geof: distance but I got this answer:
}
java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: org.openrdf.query.QueryEvaluationException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.Exception: task=ChunkTask{query=d6f6b503-fd98-4c2c-891c-afa517fd95e0,bopId=37,partitionId=-1,sinkId=38,altSinkId=null}, cause=java.util.concurrent.ExecutionException: java.lang.UnsupportedOperationException: unknown function: http://www.opengis.net/def/function/geosparql/distance

I also tried with
bif:st_distance
But I can not. Could you clarify for me please? thank you
