Runs Failing with "Self-hosted agent pool assignment is required by policy."

Incident Report for scalr.io

Postmortem

Root cause
A regression in a release deployed the morning of 2026-08-25 caused the run policy engine to incorrectly flag self-hosted agent pool assignments as non-compliant, triggering the error above even for correctly configured workspaces.

Resolution
The release was rolled back, restoring normal behavior. No customer action is required.

Preventive measures
We are adding regression test coverage for this specific scenario (self-hosted agent enforcement combined with valid pool assignment) to prevent recurrence, and reviewing our release validation process for this code path.
We apologize for the disruption this caused to your pipelines.
