[ERR_STREAM_WRITE_AFTER_END] Error from HTTP response stream produced when running

[mitsos1os]

Describe the bug
When currently running latest version, an HTTP error is produced in the console:

events.js:292
      throw er; // Unhandled 'error' event
      ^

Error [ERR_STREAM_WRITE_AFTER_END]: write after end
    at writeAfterEnd (_http_outgoing.js:668:15)
    at ServerResponse.end (_http_outgoing.js:788:7)
    at e.serveWebsite (/home/mitsos/Documents/Projects/parse-mem-captures/node_modules/nodeplotlib/dist/lib/index.js:1:3735)
    at Server.<anonymous> (/home/mitsos/Documents/Projects/parse-mem-captures/node_modules/nodeplotlib/dist/lib/index.js:1:2989)
    at Server.emit (events.js:315:20)
    at parserOnIncoming (_http_server.js:874:12)
    at HTTPParser.parserOnHeadersComplete (_http_common.js:126:17)
Emitted 'error' event on ServerResponse instance at:
    at writeAfterEndNT (_http_outgoing.js:727:7)
    at processTicksAndRejections (internal/process/task_queues.js:81:21) {
  code: 'ERR_STREAM_WRITE_AFTER_END'
}

This happens due to the fact that a request for /data/[plotId] is received from here and it reaches to an unknown endpoint so the server replies with 404.

The problem is that the request seems to be already served by here, so the error is correctly thrown
The plot is successfully drawn though...

To Reproduce
Steps to reproduce the behavior:

1. Just run a script that plots and watch the terminal
