Error resolving guardrails from DB: {e}

Error message

Error resolving guardrails from DB: {e}

What it means

Catch-all raised while resolving a policy's inherited guardrails from DB-backed policies: building temporary Policy objects from DB rows or running PolicyResolver.resolve_policy_guardrails over them failed; the original exception is embedded in the message.
