Trying to trigger an Architect flow from a Node.js service. The docs say a simple POST to /api/v2/flows/executions works, but I’m getting a 400. The body is minimal.
{"flowId": "abc-123", "inputs": {"phone": "+15550001"}}
Headers include the Bearer token and application/json. The flow exists and is published. Is there a specific input schema I’m missing? The error response is empty.
