Error message

The required parameter 'name' is empty. Rerun the command with -n flag

What it means

Returned by CommitInput.Validate when the chaincode name is empty in a 'peer lifecycle chaincode commit' invocation. The user omitted the mandatory -n flag; validation runs before any proposal is built.

Solutions

  1. Rerun with -n <chaincode-name>, e.g. -n mycc.
  2. Verify the name exactly matches the name used in approveformyorg.
  3. Check wrapper scripts for empty shell variables feeding -n.
  4. In code, set CommitInput.Name before calling Commit.

Example fix

// before
peer lifecycle chaincode commit -C mychannel -v 1.0 --sequence 1
// after
peer lifecycle chaincode commit -C mychannel -n mycc -v 1.0 --sequence 1
Defensive patterns

Strategy: validation

Validate before calling

if name == "" {
    return errors.New("chaincode name required: use -n flag")
}

Type guard

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

Try / catch

if err := run(); err != nil {
    if strings.Contains(err.Error(), "parameter 'name' is empty") {
        // prompt for chaincode name or print usage
    }
}

Prevention

When it happens

Trigger: Constructing CommitInput with Name == "" and calling Validate, e.g. running `peer lifecycle chaincode commit` without -n.

Common situations: Forgotten -n flag; script variable for the chaincode name unset/empty due to shell quoting or a failed substitution; programmatic use where the name field of the definition was not copied from the approve step.
