TimeoutError: Request timed out: method=initialize, id=1

[USeebi]

Trying to troubleshoot the error of a python wrapper from jupyter-copilot https://github.com/baolong281/jupyter-copilot/blob/main/jupyter_copilot/lsp.py. The error is coming from the function below in the wrapper.

Is there anyway I could elicit why there is no response from the server say if the server could be started manually?

node ./node_modules/@github/copilot-language-server/dist/language-server.js --stdio

    def send_request(self, method: str, params: dict) -> Any:
        """
        sends a request to the lsp and returns the response
        if a response comes then __handle_recieved_payloads will be called
        and will run the resolve or reject callback
        """
        self.request_id += 1
        self.__send_message({"id": self.request_id, "method": method, "params": params})
        result = threading.Event()
        response = {}
    
        def resolve(payload):
            response['result'] = payload
            result.set()

        def reject(payload):
            response['error'] = payload
            result.set()

        # put the callback into the map
        # when we get the response, we will call resolve or reject and the entry will be popped
        self.resolve_map[self.request_id] = resolve
        self.reject_map[self.request_id] = reject

        # 10 second timeout to prevent indefinite waiting
        # this will immediately stop blocking if the result is set by calling either resolve or reject
        result.wait(timeout=10)

        # at this point if a response has not been received then result will not be set, so we throw an error
        if not result.is_set():
            raise TimeoutError(f"Request timed out: method={method}, id={self.request_id}")

        if 'error' in response:
            raise Exception(response['error'])

        self.resolve_map.pop(self.request_id, None)
        self.reject_map.pop(self.request_id, None)
        return response['result']

You could try checking standard error. Generally initialize should always return either a result or an error. If it's timing out, that suggests a low level issue with the underlying protocol implementation.

Thanks for the comments.

I did double checked the LSP server the wrapper used by testing the copilot-lsp dist with vim and using the copilot-vim's server dist with the wrapper. Vim worked in both dist but the wrapper failed in either cases.

Can I concluded the low level issue in on the client side rather than the server side or I still miss something? Is there any similar python wrapper implementation I can make reference to troubleshoot?

Thanks again!
