I installed pylsp and all required modules. Integrated it with node server and started the service.
Everything is working as expected except when ever there is $cancelRequest from client (language client), server throws this error.

Even though the response comes, but it is noticeably slow. pylsp takes a few seconds to response after this request.

here is the sample output from my service whenever this cancel request is sent

here are my client requests and we can clearly see the response time delay:
