在WSO2 ESB 4.9.0中，我配置了一个预定的消息转发处理器，用于将消息转发到rabbitMQ消息队列。
如果我在消息处理器中配置指向ESB中的代理或API的targetEndpoint参数，然后将其发送到rabbitMQ消息队列，则它可以正常运行并且没有错误。
但是，我希望targetEndpoint直接指向外部rabbitMQ消息队列，没有代理或API解决方法。
为此，我创建了一个端点，其地址url基本上是这个（没有属性，也没有参数）：
rabbitmq:/AMQPProxy?rabbitmq.confirm.delivery=true&rabbitmq.connection.pool.size=10&rabbitmq.server.host.name=localhost&rabbitmq.server.port=5672&rabbitmq.server.user.name=guest&rabbitmq.server.password=guest&rabbitmq.queue.name=MyQueue&rabbitmq.queue.routing.key=MyQueue
然后我将消息处理器中的targetEndpoint参数指向此端点，我收到以下错误。

你能告诉我是否可以解决它以及如何解决？
