no proposal responses received

Error message

no proposal responses received

What it means

Defensive check in Approve: after iterating all endorser clients, the responses slice is empty. The code comment notes this "should only be empty due to a programming bug" — EndorserClients was initialized with zero entries — so this is an internal invariant failure, not an expected runtime condition.

Solutions

  1. Ensure Init (setPeerClients) succeeded and populated EndorserClients with at least one peer before Approve runs
  2. Check that -peerAddresses was supplied and passed validation
  3. If it persists, treat as a bug in command initialization and report with the full command invocation
