End-to-end tracing with Dash0: Passing trace headers to inngest.send?

[johanneskares]

I'd like to use Dash0 to trace my app end-to-end, from the first API call in Next.js down to my Inngest steps.

I know Next.js handles the tracestate header for standard fetches, but I'm unsure how to bridge this gap when triggering an Inngest function.

When I run this:

await inngest.send({
    name: "my-event",
    data: {},
});

Is it possible to pass a parent trace/span ID manually? Or can I make the Inngest Server automatically pick up the tracestate header from the fetch that happens internally?
