I'm using this with these
local connectionParams = {
host = "localhost",
port = 5672,
username = "guest",
password = "guest",
vhost = "/",
role = "publisher",
exchange = 'exchange',
ssl = false,
}
-- Connect to RabbitMQ with retries
local conn = RabbitMQPublisher.connectWithRetries(connectionParams, 5, 3)
RabbitMQPublisher.publishMessage(conn, json_message, routingKey)
-- Close the RabbitMQ connection
RabbitMQPublisher.closeConnection(conn)
