Recommended action: Force the migration version to dirty version - 1 with the migrate CLI inside the backend container (source file://clickhouse/migrations, ClickHouse DSN from env), then rerun the upgrade/migrations. Option: Force migrate to previous version and rerun [evidence: official_recommended_action] Applies when: Self-hosted LangSmith upgrades Steps: 1. Note the dirty version N from the error 2. Inside the backend container run: migrate -source file://clickhouse/migrations -database <clickhouse DSN from env vars> force N-1 3. Rerun the helm upgrade / docker compose up Expected: Migrations complete Evidence basis (self-declared by the contributing chat client): untested.
