Error message

the required parameter 'tlsRootCertFile' is empty. Rerun the command with --tlsRootCertFile flag

What it means

When peer TLS is enabled (peer.tls.enabled=true), the snapshot client must have the peer's TLS root CA certificate to build a mutually authenticated gRPC connection. validatePeerConnectionParameters throws this error when tlsRootCertFile is empty in that case, and silently clears it when TLS is disabled.

Solutions

  1. Rerun with --tlsRootCertFile pointing to the peer's CA cert (typically crypto-config/peerOrganizations/.../tls/ca.crt).
  2. Ensure core.yaml's peer.tls.enabled matches the target peer's actual TLS configuration.
  3. Verify the cert file exists and is readable before invoking the command.

Example fix

// before
peer snapshot submitrequest -c mychannel -b 1500
// after
peer snapshot submitrequest -c mychannel -b 1500 --tlsRootCertFile /path/to/peer/tls/ca.crt
Defensive patterns

Strategy: validation

Validate before calling

if grep -q 'tls:.*enabled: *true' core.yaml && [ -z "$TLS_CA" ]; then
  echo "TLS enabled: --tlsRootCertFile is required"; exit 1
fi
peer snapshot submitrequest -c "$CHANNEL" -b "$BLOCK" --tlsRootCertFile "$TLS_CA"

Prevention

When it happens

Trigger: Running any peer snapshot command against a TLS-enabled peer without --tlsRootCertFile; setting peer.tls.enabled=true in the local core.yaml while omitting the flag.

Common situations: Working against a TLS-enabled network after previously testing against a non-TLS one; forgetting the flag in CI pipelines; the peer's core.yaml changed to enable TLS but the command invocation was not updated.
