  eventData = { ...eventData, properties: { ...eventData.properties } };

  const traceParent = getTraceParentHeader(span.context());
  if (traceParent) {

      if (traceParentHeader) {
        request.headers.set("traceparent", traceParentHeader);
        const traceState = spanContext.traceState && spanContext.traceState.serialize();
        // if tracestate is set, traceparent MUST be set, so only set tracestate after traceparent
        if (traceState) {
          request.headers.set("tracestate", traceState);
        }
      }
