Binary injection failed

[gy1005]

It seemed that tracer:binary_inject() didn't inject the span context to the carrier when I replaced tracer:text_map_inject() function in the tutorial.lua with it. carrierturned out to be an empty string and span_context is nil. Any idea on that?

local carrier = tracer:binary_inject(parent_span:context())
local span_context = tracer:binary_extract(carrier)
assert(span_context ~= nil)

While tracer:text_map_inject() and tracer:http_headers_inject() worked perfectly for me.

Which tracer are you using?
