NextJS after - Compatibility with vercel/otel?

[websaid]

SUMMARY

NextJS 15.1 made the after function stable: https://nextjs.org/docs/app/api-reference/functions/after

I tried the following code in my page.tsx:

  after(() => {
    trace.getActiveSpan()?.addEvent("Page streaming finished")
  });

I get the following error Can not execute the operation on ended Span.

My wondering: Could it be that @vercel/otel is ending the span before potentially running the after function?

@websaid apologies for the delay here. I can't seem to reproduce this. Can you share a reproduction please?
