Atomic increment for nested map

I tried the following command and that didn’t work either MapOperation.put(mapPolicy, “map”, Value.get(“count”), Value.get(10), CTX.mapKey(Value.get(“123”))))

and I get the following error : com.aerospike.client.AerospikeException: Error 26,1,30000,5000,1,BB9979897BC230A 172.17.35.56 3000: Operation not applicable
