[Node.JS] Memory leak - Server reaches 100% memory after 5 or 6 days

const http = require('http');
const https = require('https');

      const requestTimeout = setTimeout(() => {
        res.writeHead(408, {'Content-Type': 'text/plain'});
        res.end('Request Timeout');
      }, 5000); // Set a timeout of 5 seconds for the request

      const response = await new Promise((resolve, reject) => {
        client.get(url, resolve).on('error', reject);

      clearTimeout(requestTimeout); // Clear the timeout if the request completes before the timeout is reached
      const buffer = Buffer.concat(chunks);
      const model = await nsfw.load(); // To load a local model, nsfw.load('file://./path/to/model/')

      const image = await tf.node.decodeImage(buffer, 3);
      const predictions = await model.classify(image);
      image.dispose(); // Tensor memory must be managed explicitly (it is not sufficient to let a tf.Tensor go out of scope for its memory to be released).
      console.log(predictions);
      res.writeHead(200, {
