Is there a required condition?\r\n\r\nalways\r\n\r\n### What is the expected behavior? Why is that the expected behavior?\r\n\r\nBoth will be LISTENED to, or if there is a specification for the order, that document will be clearly noted.\r\n\r\n### What do you see instead?\r\n\r\nno outputs\r\n\r\n### Additional information\r\n\r\nFor example, this is how it is used.\r\nhttps://github.com/Azure/static-web-apps-cli/blob/352be8f4ce2d01e1dac17797a80f9f414d612bc0/src/msha/server.ts#L173-L174","author":{"url":"https://github.com/yamachu","@type":"Person","name":"yamachu"},"datePublished":"2024-05-29T17:41:24Z","url":"https://github.com/nodejs/node/issues/53204"}
