url supplied to nest.js project:

amqp://localhost:5672/VIRTUAL_HOST_NAME?heartbeat=30

Line 229 of AmqpConnectionManager.js:

originalUrl = url;
connect = {
    ...url,
    // heartbeat: (_a = url.heartbeat) !== null && _a !== void 0 ? _a : this.heartbeatIntervalInSeconds, -> original code
    heartbeat: 30 -> my edits
};

Is there some way to auto set heartbeat variable directly?
