How do I propagate OTEL context into a Worker?

First, should I expect that the context is propagated via postMessage to Workers automatically?

I assumed not, so I've tried using

propagation.inject/extract

propagation.inject/extract

with a plain object as the carrier to pass the context in the message of

postMessage

postMessage

.

It appears that the carrier doesn't contain any data, when using Deno's native OTEL.

I've tried also using the

NodeSDK

NodeSDK

directly too with Deno OTEL disabled, and the carrier does appear to have a

traceparent

traceparent

.

Has anyone else managed to propagate into a Worker?
Does this seem to be a bug in Deno?
