How to have a single trace_id for child Sidekiq jobs

[DavidBlau854]

Hey,
I am trying to have a relation between parent and child Sidekiq Jobs. e.g:

jobOne creates jobTwo creates jobThree etc.

Currently each job receives its own trace_id, and a traceparent with the parent job trace.

To be able to easily track the subsequent jobs I want them all to have the same trace_id.
( I am logging the trace_id for every log and if all would have the same trace_id it would make our life much easier tracking the flow of the request through the various jobs)

I tried reading the traceparent and setting it as a current trace_id for the child job but couldn't.

After more trial and error I tried creating a child span with this sidekiq middleware (below)
Im still getting errors and generally not sure I'm doing the right thing here..

Maybe I should just change the Sidke otel configuration or something like this?
Can anyone please assist?

# Sidekiq middleware for using traceparent from the parent job
module Middleware
  class OpenTelemetryTraceMiddleware
    def call(worker, job, queue)
      traceparent = job['traceparent']

      if traceparent
        version, trace_id, span_id, trace_flags = traceparent.split('-')

        trace_id = [trace_id].pack('H*')
        span_id = [span_id].pack('H*')
        trace_flags = trace_flags.to_i(16)
        span_context = OpenTelemetry::Trace::SpanContext.new(
          trace_id: trace_id,
          span_id: span_id,
          trace_flags: trace_flags,
          remote: true
        )
        tracer = OpenTelemetry.tracer_provider.tracer('default')
        tracer.start_span("test", with_parent: span_context) do |span|
          yield
        end

      else
        # No traceparent found, proceed with the job normally
        yield
      end
    end
  end
end

My project setup:
ruby '2.6.8'
'rails', '5.2.6'
gem 'opentelemetry-sdk', '1.2' # installing version 1.2 to avoid bug on higher versions that was fixed only on ruby 3.0 ->#1495
gem 'opentelemetry-exporter-otlp'
gem 'opentelemetry-instrumentation-all', '0.30.0' # installing version 0.30.0 since higher version internally depend on Rails 6 --> #1050 (comment)

than simply calling:

  OpenTelemetry::SDK.configure do |c|
    c.use_all
  end

Thanks a lot in advance for any help!!

using this:
c.use 'OpenTelemetry::Instrumentation::Sidekiq', propagation_style: :child
