Defined in:

Overview

Raised when restoring a persisted payload whose schema_version does not match the workflow's current persistence_schema_version AND no migration block is registered to bridge the gap. Hosts fix this by adding migrate_from(stored) do |payload| ... end to the workflow class, or by bumping persistence_schema_version to match the stored version. Downgrades (stored > current) always raise; Smith has no rollback semantics.
