 HI ,

I have seen the code of WS of version 3.0.0 rc1 and found that WS is not able to decode the IE Trace information correctly.

Observation :
1. Trace info has parameter 
    uint32_t Traceid:24, 
    uint32_t spare;
WS does not decoded the spare value .

static void
  dissect_pfcp_trace_information(tvbuff_t *tvb, packet_info *pinfo _U_, proto_tree
  *tree, proto_item *item _U_, guint16 length _U_, guint8 message_type _U_, pfcp_
  session_args_t *args _U_){


/* 8 to 10   Trace ID */
      proto_tree_add_item(tree, hf_pfcp_trace_information_trace_id, tvb, offset, 3
  , ENC_BIG_ENDIAN);
      offset += 3;    ========offset+=4 should be there.
}

2. IP_address 

proto_tree_add_item(tree, hf_pfcp_trace_information_ipaddress, tvb, offset, 
  length_ipaddress, ENC_NA);
      offset += length_ipaddress; Here also , offset += wrong value it should be fixed with length_ipaddress*sizeof(uint8_t)

Thanks
