What happened

Volume operation rejected (E_VOLUME_RELAY_UNKNOWN): {detail}. This is the receipt’s what text, produced by the node’s ExecutionError::RasVolume. Placeholders in braces are filled from the failing transaction.

Why it happened

The node rejected the operation with E2006 (category storage, Storage). The receipt’s why field carries the specific cause and context carries structured details, such as the values that filled the placeholders above. The normative rule is in CIP-9.

How to fix

An explicitly supplied relay is not in the relay registry. Use node_ids from the registry, or omit relay_nodes to let the chain auto-assign — which needs erasure_k + erasure_m Active relays with room, and reports E2005 if the registry cannot supply them. The receipt’s detail names the node_id.
