Can't create a valid SpanContext from data of another SpanContext

[Shlomo-Stein-LS]

Hi guys, I need your help,
I'm having trouble creating a new SpanContext obj from data I saved earlier that I got from another SpanContext.

Here is my code:

// Creating a new span
nostd::shared_ptr<trace::Span> openSpan = GetTracer(name)->StartSpan(name);

// Getting data from context
trace::SpanContext context = openSpan ->GetContext();
const uint8_t* traceId = context.trace_id ().Id ().data (); // ----> traceId contains garbage data
const uint8_t* spanId = context.span_id ().Id ().data (); // ----> spanId contains garbage data
uint8_t flags = context.trace_flags().flags ();
// FYI, I'm passing that data to a different service

// Initializing a new Span context from the parameters
void createSpanContext (uint8_t* trace_id, uint8_t* span_id, uint8_t trace_flags)
{
nostd::span<const uint8_t, trace::TraceId::kSize> traceIdData (trace_id, trace::TraceId::kSize);
nostd::span<const uint8_t, trace::SpanId::kSize> spanIdData (span_id, trace::SpanId::kSize);

trace::TraceId traceId (traceIdData);
trace::SpanId spanId (spanIdData);
trace::TraceFlags flags (trace_flags);

trace::SpanContext newContext (traceId, spanId, flags, false);
........
}

I can't figure out why I'm getting garbage data from the SpanContext
Please help, tell me what I'm doing wrong.

What do you mean by saying "garbage data"? TraceID and SpanID are binary data and are not printable.The only invalid value is all zero.

I figured out the issue, it seems like I did not parse the data correctly.
Thanks anyways
