could not get channelconfig for channel '%s'

Error message

could not get channelconfig for channel '%s'

What it means

validateInput needs the stable channel config to obtain the MSP manager and verify collection configs. GetStableChannelConfig returned nil for i.ChannelID, meaning the peer has no usable channelconfig bundle for that channel at this moment.

Solutions

1. Confirm the channel name is correct and the peer has joined it (peer channel list)
2. Join the peer to the channel before running lifecycle approve/commit
3. Retry after channel config propagation completes if the channel was just created

Example fix

// before
peer lifecycle chaincode approveformyorg -C chanel1  # typo
// after
peer channel list  # verify joined channels
peer lifecycle chaincode approveformyorg -C mychannel

// shell: confirm membership before lifecycle ops
peer channel list | grep -q "mychannel" || { echo "peer not joined to mychannel"; exit 1; }

if err != nil && strings.Contains(err.Error(), "could not get channelconfig") {
    // check channel name and peer channel membership
}

When it happens

Trigger: Invoking approve/commit with a channel ID the peer has not joined, or a channel whose config bundle is not yet available on this peer.

Common situations: Typo'd channel name in the peer command, invoking on the wrong peer (one not joined to the channel), or racing channel creation/join before config is propagated.
