key unsupported: raw artifat does not have key

Error message

key unsupported: raw artifat does not have key

What it means

RawArtifact.GetKey is unconditionally unsupported: raw artifacts are inline string data with no storage key. Any key-based artifact lookup that reaches a raw artifact fails here. (Note the source's typo 'artifat'.)

Solutions

1. Do not use key-based access with raw artifacts; the data is inline
2. Use s3/gcs/azure/oss artifacts when a key is needed
