The required parameter 'channelID' is empty. Rerun the comma

Error message

The required parameter 'channelID' is empty. Rerun the command with -C flag

What it means

Input validation guard in CommitInput.Validate for the `peer lifecycle chaincode commit` CLI: it rejects the commit definition proposal when the channel ID is an empty string, i.e. the user omitted the required -C flag. Nothing has been sent to peers at this point; the command aborts before building the proposal.

Solutions

1. Rerun the command with the -C flag, e.g. -C mychannel.
2. Ensure the channel is actually joined (peer channel list) since the flag value must match a real channel.
3. If using a wrapper script, confirm it forwards the channel argument.
4. When building CommitInput in code, set ChannelID before calling Commit.

Example fix

// before
peer lifecycle chaincode commit -o orderer:7050 --name mycc -v 1.0
// after
peer lifecycle chaincode commit -o orderer:7050 --name mycc -v 1.0 -C mychannel

if channelID == "" {
    return errors.New("channelID required: use -C flag")
}

func hasChannel(c *CommitInput) bool { return c != nil && c.ChannelID != "" }

if err := run(); err != nil {
    if strings.Contains(err.Error(), "channelID' is empty") {
        // re-run with -C or print usage
    }
}

When it happens

Trigger: Calling CommitCmd-backed code (or constructing CommitInput directly) with ChannelID == "" and invoking Validate.

Common situations: Forgot the -C flag on `peer lifecycle chaincode commit`; environment variable/flag wiring (CORE_PEER_LOCALMSPID-style viper bindings) dropped the channel value; SDK scripts building CommitInput programmatically omitting ChannelID.
