key unsupported: cannot set key for raw artifact

Error message

key unsupported: cannot set key for raw artifact

What it means

RawArtifact represents inline string data placed directly in the spec, so it has no external storage location; its GetKey/has-key validation rejects any attempt to assign an artifact key to a raw artifact. This fires when a workflow spec sets a key field on a RawArtifact, an operation that is meaningless because the content is embedded, not fetched from a keyed source.
