MissingMetadataField

§

MalformedComponent

A well-known component in the AppData dictionary failed to decode — surfaced by the migrated-group read paths when a component’s wire bytes can’t be parsed.

Structured rather than a flat String so downstream consumers (bindings, error mapping) can match on the offending component_id to discriminate failure modes without parsing a display string. component_id is Option because the upstream ComponentSourceError has a few variants that don’t carry one (e.g. wrapped legacy-metadata errors); those map to None. The inner reason is diagnostic-only — typically a formatted ComponentSourceError — and should not be matched against.

Fields

§component_id: Option<ComponentId>

Component whose wire bytes failed to decode. None for errors that don’t originate at a specific component.

§reason: String

Diagnostic string (display-only; not a stable API).
