[web-shared] Fix trace viewer step spans for v1 events by karthikscale3 · Pull Request #1406 · vercel/workflow

karthikscale3 · 2026-03-16T20:55:59Z

Changes

V1 runs (pre-event-sourcing) don't emit step_created events. stepEventsToStepEntity was returning null for every step group, so v1 runs showed only the root run span with no steps underneath.

Fix: fall back to the earliest event in the group (e.g. step_started) when step_created is missing. Step name will be empty for v1 since it was only available on step_created.eventData, but the spans render correctly with proper status and timing.

Wall Time: Total testbench time (trigger workflow + poll for result)
Overhead: Testbench overhead (Wall Time - Workflow Time)
Samples: Number of benchmark iterations run
vs Fastest: How much slower compared to the fastest configuration for this benchmark
