RabbitMQ Nodes must be valid JSON

Error message

RabbitMQ Nodes must be valid JSON: ${e.message}

What it means

validate() runs JSON.parse on rabbitmqNodes for RabbitMQ monitors. It must be valid JSON (typically an array of node URLs).

Solutions

1. Provide rabbitmqNodes as valid JSON matching the expected shape
2. Validate with JSON.parse before saving

if (monitor.rabbitmqNodes) { JSON.parse(monitor.rabbitmqNodes); } // throws if invalid

function isValidJsonField(v) { if (!v) return true; try { JSON.parse(v); return true; } catch { return false; } }

try { monitor.validate(); await save(monitor); } catch (e) { /* surface e.message */ }

When it happens

Trigger: rabbitmqNodes contains a non-JSON string (comma-separated nodes, plain text).

Common situations: Pasting node list as newline- or comma-separated text instead of a JSON array.
