[e2e] Fix step source maps assertion for Vercel production#1672VaguelySerious merged 1 commit intomainfrom
Conversation
ESM step bundles (#1562) now preserve inline source maps on Vercel production, so the production early-return in hasStepSourceMaps() is stale and causes all E2E Vercel Prod Tests to fail. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Human: so I don't know whether this was originally intention or not, but since moving to ESM for workflow bundling on
main, we now have source maps for steps, which we previously didn't. Did we disable them intentionally?Summary
WORKFLOW_VERCEL_ENV === 'production'early return inhasStepSourceMaps()that assumed step error stacks don't contain original TypeScript filenames on Vercel production.tsfilenames (e.g.99_e2e.ts,helpers.ts)mainsince [builders] Switch Vercel Build Output API from CJS to ESM #1562 was merged (every BOA framework: express, hono, fastify, nitro, nuxt, vite, astro, example)Root cause
hasStepSourceMaps()returnedfalsefor all Vercel production tests, making the e2e tests assertexpect(result.stack).not.toContain('99_e2e.ts'). But ESM step bundles withsourcemap: 'inline'now produce stacks with original filenames on production, so the assertion fails.The PR branch CI for #1562 passed because
WORKFLOW_VERCEL_ENVis set topreviewon branches (notproduction), and the preview code path already returnedtruefor non-sveltekit apps.Test plan
