peer '%s' doesn't have associated peer config

Error message

peer '%s' doesn't have associated peer config

What it means

appendPeerConfig looks up the requested peer name in the connection profile's NetworkConfig.Peers map. This error means the peer name passed (via --targetPeer or a channel peer entry) does not exist in the loaded connection profile.

Solutions

1. List the peers section of your connection profile and use an exact matching name for --targetPeer
2. Confirm the correct connection profile file is being loaded (check the path in --connectionProfile)
3. Fix spelling/case — profile peer keys are matched exactly

Example fix

// before
--targetPeer peer0.orgX.example.com:7051   // not in cp.yaml
// after
--targetPeer peer0.org1.example.com:7051   // exact key from cp.yaml "peers"

cfg, _ := ccp.LoadConfig(profilePath)
if _, ok := cfg.Peers[targetPeer]; !ok { return fmt.Errorf("peer %q not in connection profile", targetPeer) }

func peerInProfile(n *common.NetworkConfig, peer string) bool { _, ok := n.Peers[peer]; return ok }

if err := run(cmd); err != nil && strings.Contains(err.Error(), "doesn't have associated peer config") { log.Fatalf("peer %s missing from profile; check exact key spelling", targetPeer) }

When it happens

Trigger: --targetPeer value is not a key in the profile's "peers" section, or the channel-less lookup uses a name that doesn't match the YAML exactly.

Common situations: Typo or case mismatch between --targetPeer and the profile peer name; profile loaded is for a different organization/network than expected; stale profile missing a recently added peer.
