could not get channel config for channel '%s'

Error message

could not get channel config for channel '%s'

What it means

This error is returned by ValidatorCommitter.ImplicitCollectionEndorsementPolicyAsBytes in core/chaincode/lifecycle/deployedcc_infoprovider.go:268 when GetStableChannelConfig(channelID) returns nil. It means the lifecycle layer could not obtain a stable snapshot of the channel's configuration while resolving the implicit collection endorsement policy for an org. It is returned as unexpectedErr (not validationErr), signaling an infrastructure/state problem rather than a bad transaction.

Solutions

1. Verify the channelID passed to the transaction matches a channel the peer has actually joined (peer channel list).
2. Re-check that the channel config source is initialized and the channel exists in the ledger before invoking.
3. Restart/re-sync the peer so channel resources are recreated if the channel was recently modified.
4. If transient (channel update in flight), retry the transaction after the channel stabilizes.

// Go: before invoking, verify the peer knows the channel
channels, _ := peerChannelList()
found := slices.Contains(channels, channelID)
if !found { return fmt.Errorf("channel %s not joined", channelID) }

func hasChannelConfig(src ChannelConfigSource, ch string) bool { return src.GetStableChannelConfig(ch) != nil }

if unexpectedErr != nil {
  if strings.Contains(unexpectedErr.Error(), "could not get channel config") {
    // recover: verify channel exists / retry after channel resources ready
  }
}

When it happens

Trigger: Called via CollectionValidationInfo when validating a transaction that touches an implicit collection (_implicit_org_<MSPID>) and the channel config channel does not exist in the channel config source (e.g. channel not loaded, wrong channelID, ledger/channel being closed or torn down).

Common situations: Transactions referencing a channel that no longer exists or was renamed; peer joining/leaving a channel concurrently; a channelID typo in SDK invocation; peer has not fetched channel config yet during startup.
