Error message
provide --messaging-group-id, or --channel-type and --platform-id to resolve it
What it means
When creating a wiring, if --messaging-group-id is absent the CLI tries to resolve the group from --channel-type + --platform-id; if either is missing too, it throws this.

Solutions
- Pass --messaging-group-id directly (get it from `ncl messaging-groups list`)
- Or pass both --channel-type <type> and --platform-id <id> (plus optional --instance)
Example fix
# before ncl wirings create --agent-group myagent --channel-type discord # after ncl wirings create --agent-group myagent --channel-type discord --platform-id 123456789
Defensive patterns
Strategy: validation
Validate before calling
if (!mgId && !(channelType && platformId)) {
throw new Error('need --messaging-group-id or --channel-type + --platform-id');
} Prevention
- Wrap ncl wirings create in a script that checks required flags first
When it happens
Trigger: ncl wirings create with neither --messaging-group-id nor both --channel-type and --platform-id.
Common situations: Assuming the channel is implied by the agent group, or providing only --channel-type without the platform id.
