[createProLaunchBroadcast] Resend response missing id

Error message

[createProLaunchBroadcast] Resend response missing id: ${JSON.stringify(json)}

What it means

Response-shape guard after a successful Resend broadcast create: the JSON body parsed (or failed to parse) without an `id` field. Without a broadcast id the caller cannot preview, send, or track the broadcast, so the action refuses to return a result — even though Resend may actually have created the broadcast.

Solutions

1. Check the Resend dashboard for a broadcast matching the request — it may exist despite the unparseable response
2. Treat as a Resend API contract change: inspect the logged JSON and adapt the parser if the field was renamed
