fix(world-vercel): include runId in streams.get() request URL by TooTallNate · Pull Request #1676 · vercel/workflow

TooTallNate · 2026-04-09T22:28:47Z

Summary

Fix streams.get() in @workflow/world-vercel to pass runId through to getStreamUrl() instead of hardcoding undefined, which was causing all stream read requests to hit /api/v2/stream/:streamId instead of /api/v2/runs/:runId/stream/:streamId
Remove the fallback code path in getStreamUrl() that allowed omitting runId — the parameter is now required as string (was string | undefined)

The health check case is unaffected since it already generates a synthetic runId via generateHealthCheckRunId() — the bug was just that get() was discarding it.

Pull request overview

Fixes @workflow/world-vercel stream reads by ensuring streams.get() includes the runId in the generated request URL, aligning the client with the /v2/runs/:runId/stream/:streamId endpoint shape.

Changes:

Make getStreamUrl() require runId: string and remove the no-runId fallback URL shape.
Fix streams.get() to pass through its runId parameter instead of discarding it.
Add a changeset for a patch release of @workflow/world-vercel.

File	Description
packages/world-vercel/src/streamer.ts	Corrects stream read URL construction to include `runId` and removes legacy fallback path.
.changeset/fix-stream-get-runid.md	Announces a patch release documenting the bug fix.

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

streams.get() was ignoring the runId parameter and hardcoding undefined, causing requests to hit /api/v2/stream/:streamId instead of the correct /api/v2/runs/:runId/stream/:streamId. Also removes the fallback path in getStreamUrl() that allowed omitting runId.
