InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.

这个错误通常是因为 WebSocket 连接还没有完成，就尝试发送消息。你需要确保 WebSocket 连接已经完成并且处于打开状态，才能发送消息。你可以在 WebSocket 的 onopen 回调函数中发送消息，以确保连接已经打开。另外，你还需要确保你正在使用正确的协议和端口来连接 WebSocket 服务器。

Error in v-on handler (Promise/async): "InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state

这个错误通常是因为 WebSocket 连接还没有完成就试图通过它发送消息。你可以在 WebSocket 的 onopen 事件处理程序中发送消息，以确保连接已经建立。另外，你也要确保 WebSocket 的状态是 OPEN 才能发送消息，因为在 CONNECTING 或 CLOSING 状态下发送消息会导致该错误。以下是一个在 WebSocket 连接完成后发送消息的示例代码：

const socket = new WebSocket('ws://example.com');
socket.onopen = () => {
  console.log('WebSocket connection established');
  socket.send('Hello, server!');
};
socket.onerror = (error) => {
  console.error('WebSocket error:', error);
};
socket.onmessage = (event) => {
  console.log('Received message:', event.data);
};

在该示例中，我们在 WebSocket 的 onopen 事件处理程序中发送了一条消息，并在控制台中打印了收到的消息。如果出现错误，我们将在控制台中记录它。

workers: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state..

As an AI language model, I do not have access to your specific code or context, so I can only provide general information about this error.

The "InvalidStateError" message typically indicates that the browser is trying to register a service worker in a state where it is not allowed. For example, service workers can only be registered on secure origins (HTTPS or localhost), and may not work correctly in certain browser contexts such as incognito mode.

To troubleshoot this error, you can try the following steps:

1. Check that your website is being served over HTTPS or on localhost. If not, you'll need to secure your site to use service workers.

2. Make sure that your code for registering the service worker is being called in the correct context. For example, the registration code should not be called before the page has finished loading.

3. Check the browser console for any other error messages that may be related to the invalid state error.

4. If you are still having issues, try testing your code in a different browser or context to see if the issue is specific to your environment.

If none of these steps resolve the issue, you may need to seek additional help in troubleshooting the specific code and context of your application.
