I have an application that is sending messages through AWS Services and I am manually adding the headers to the message via,
final Map<String, Object> braveHeaders = new HashMap<>();
braveHeaders.put(Span.TRACE_ID_NAME, span.getTraceId());
braveHeaders.put(Span.PARENT_ID_NAME, span.getParents().stream().findFirst().orElse(0L));
braveHeaders.put(Span.SAMPLED_NAME, span.isExportable());
braveHeaders.put(Span.SPAN_FLAGS, span.getBaggage());
braveHeaders.put(Span.SPAN_NAME_NAME, span.getName());
braveHeaders.put(Span.SPAN_EXPORT_NAME, span.getName());
braveHeaders.put(Span.SPAN_ID_NAME, span.getSpanId());
On the consumer application I am attempting to read the attributes and build a new Span,
JsonNode braveTree = objectMapper.readTree(brave.asText());
// configure a function that extracts the trace context from a request
TraceContext.Extractor<JsonNode> extractor = tracing.propagation().extractor(
(carrier, key) -> carrier.get(key).asText());
// when a server receives a request, it joins or starts a new trace
Span span = tracing.tracer().nextSpan(extractor.extract(braveTree));
The headers are being successfully extracted from the Headers but it will fail when parsing the parseSpanId due to invalid length causing the creation of the new TraceContext to fail.
/** Parses the span id from the input string. Returns true if the ID is valid. */
final <C, K> boolean parseSpanId(Propagation.Getter<C, K> getter, C carrier, K key) {
String spanIdString = getter.get(carrier, key);
if (isNull(key, spanIdString)) return false;
int length = spanIdString.length();
if (invalidIdLength(key, length, 16)) return false;
spanId = lenientLowerHexToUnsignedLong(spanIdString, 0, length);
if (spanId == 0) {
maybeLogNotLowerHex(key, spanIdString);
return false;
}
return true;
}
Is there any method to continue a span when receiving headers from Sleuth 1.3 > 2.0? Or must all applications be on the same version?
