    WARNING! It looks like you're using OpenTelemetry but you didn't install an instrumentation for the concurrent-ruby gem.
    sbmt-strangler runs your code using concurrent-ruby futures in mirror mode, so this is very adviced to install
    the instrumentation (opentelemetry-instrumentation-concurrent_ruby gem) to get traces in mirror mode!
