How to propagate span context from one autoinstrumented span into next. E.g. express `instrumentation-http` into `instrumentation-nestjs-core`?

I'm not sure what you're asking here. Baggage and trace ids are propagated by context. I think you may be using hte term "context" in a way we don't normally use it. Can you please explain your use case a little further or provide a code example?

I solved this by removing instrumentation-nestjs-core.

Basically I have a custom startSpan function where I am doing trace.getActiveSpan() and getting attributes of "parent" span for propagation into new custom span.

Problem is that there is no interface for instrumentation-nestjs-core to also do this custom attribute propagation when it's autoinstrumented span is generated, thus stopping the chain. And I think baggage here wouldn't help much either.
