Function extractContext

extractContext<T extends Record<string, unknown>>(
    params: T,
): {
    context: Context;
    params: Omit<T, "traceparent" | "tracestate" | "baggage">;
}
Extract an OpenTelemetry Context from workflow params using the globally registered textmap propagator (W3C TraceContext + Baggage by default).

Unlike extractTraceparent, which only pulls out raw strings, this function returns a fully hydrated Context that can be passed as a parent to tracer.startActiveSpan() or withTrace().

The returned params are cleaned of all propagation keys (traceparent, tracestate, baggage, …).
Type Parameters
- T extends Record<string, unknown>
Parameters
- params: T
  The params object containing propagation headers.
Returns { context: Context; params: Omit<T, "traceparent" | "tracestate" | "baggage"> }
An object with the extracted context and cleaned params.
Example
```
const { params: clean, context: parentCtx } = extractContext(event.payload);
tracer.startActiveSpan("my-span", {}, parentCtx, (span) => { ... });
```
