Sentry Crash Spike to Dependency Pin-Back PR
When Sentry shows an error spike tied to a recent dependency bump, this correlates the failing release to the package change and opens a GitHub PR that pins the dependency back…
How it runs
The automated pipeline, trigger to output.
- TriggerSentry alert for spiking high-frequency issueSentry
- ActionResolve the release and diff its lockfile against the prior releaseGitHub
- LogicConfirm a single suspect bump correlates with the spike window
- ActionOpen a GitHub PR pinning the package back to last known-goodGitHub
- OutputAlert on-call in Slack with the pin-back PR and evidenceSlack
What it does
Closes the loop between a bad upgrade and the rollback. When a Sentry issue spikes right after a release, it inspects which dependency changed in that release and drafts a GitHub pull request reverting that single package to its previous pinned version.
When to use it
Use it when an upgrade slips through CI but breaks in production — and you want a one-click revert path rather than a manual git archaeology session at 2am. Best for teams that deploy frequently and tag releases.
How it works
- 1A Sentry alert for a new high-frequency issue triggers the workflow.
- 2The flow reads the release the errors are attached to and diffs that release's lockfile against the prior release to find changed dependencies.
- 3A decision step checks whether exactly one suspect package bump correlates with the spike window; if not, it routes to human review instead of auto-acting.
- 4For a confident match it opens a GitHub PR pinning the package back, linking the Sentry issue and error count in the description.
- 5It pings the on-call channel in Slack with the proposed pin-back and the evidence.
