The required parameter 'sequence' is empty. Rerun the comman
Error message
The required parameter 'sequence' is empty. Rerun the command with --sequence flag
What it means
Returned by CommitInput.Validate when the sequence number is zero/unset for a commit invocation — the mandatory --sequence flag was omitted. Sequence is the definition's ledger sequence and must be a positive integer.

Solutions
- Rerun with --sequence set to the approved definition's sequence, e.g. --sequence 1.
- Run `peer lifecycle chaincode queryapproved -C mychannel -n mycc` to find the sequence.
- For upgrades, increment the sequence from the previous commit.
- In code, set CommitInput.Sequence before calling Commit.
Example fix
// before peer lifecycle chaincode commit -C mychannel -n mycc -v 1.0 // after peer lifecycle chaincode commit -C mychannel -n mycc -v 1.0 --sequence 1
Defensive patterns
Strategy: validation
Validate before calling
if sequence == 0 {
return errors.New("sequence required: use --sequence flag")
} Type guard
func hasSequence(c *CommitInput) bool { return c != nil && c.Sequence > 0 } Try / catch
if err := run(); err != nil {
if strings.Contains(err.Error(), "parameter 'sequence' is empty") {
// re-run with --sequence from queryapproved
}
} Prevention
- Always pass --sequence; use 1 for the first commit.
- Run queryapproved to confirm the current sequence before committing.
- Increment the sequence for each upgrade.
When it happens
Trigger: Constructing CommitInput with Sequence == 0 and calling Validate — e.g. `peer lifecycle chaincode commit` run without --sequence.
Common situations: First commit forgetting --sequence 1; subsequent upgrades reusing an old sequence; not checking queryapproved for the next expected sequence.
