Vercel Preview Error-Watch Rollup Gate
After a Vercel preview deploys, exercises the preview with smoke traffic, watches Sentry for new errors triggered against that release.
How it runs
The automated pipeline, trigger to output.
- TriggerVercel preview deployment succeededVercel
- ActionDrive smoke traffic across preview routesHTTP webhook
- ActionQuery Sentry for issues on this releaseSentry
- LogicPass/fail on presence of new errors
- OutputPost error rollup and set error-watch commit statusGitHub
What it does
Catches runtime errors a preview only surfaces under traffic. The workflow pings the preview's main routes to generate activity, waits a short window, then queries Sentry for issues tagged to that preview release. Any new, unresolved errors become a blocking PR comment listing the exception, count, and stack link so the author can fix before merge.
When to use it
Use it when build-green and smoke-200 still let runtime exceptions slip through, especially for code paths that only throw when actually invoked. Requires Sentry releases tagged with the preview's commit SHA.
How it works
- 1Vercel sends a deployment-succeeded webhook for a preview build with its commit SHA.
- 2An HTTP step drives smoke traffic across the preview's key routes.
- 3Sentry is queried for issues scoped to the matching release after a short settle window.
- 4Logic decides pass or fail based on whether any new unresolved errors exist.
- 5GitHub gets an `error-watch` commit status and, on failure, a rollup comment of the new exceptions with links into Sentry.
