Why is the body of the POST request not coming?

Question

JavaScript

I'm trying to write a layer to proxy all requests to the server.
On the server In a router in a switch I disassemble methods.
app.use('/api/*', router);

case 'GET':
      request
        .get(config.apiUrl + req.originalUrl)
        .set('Content-Type', req.headers['content-type'] || 'application/json')
        .set('Authorization', req.headers['authorization'])
        .end((err, response) => {
          if(err) {
            if(err.code === 'ECONNREFUSED') {
              res.status(500).send(err);
              return;
            }
            res.status(err.status).send(err.error)
            return;
          }
          res.status(response.status).send(response.body)
        });
      break;

case 'POST':
      request
        .post(config.apiUrl + req.originalUrl)
        .send(req.body)
        .set('Content-Type', req.headers['content-type'] || 'application/json')
        .set('Authorization', req.headers['authorization'])
        .end((err, response) => {
          if(err) {
            if(err.code === 'ECONNREFUSED') {
              res.status(500).send(err);
              return;
            }
            res.status(err.status).send(err.error)
            return;
          }
          res.status(response.status).send(response.body)
        });
      console.log("Method POST", req.params, req.query, req.body);
      break;

Request from the client side

fetch('/api/сфдд', {
    method: 'post',
    headers: {
      'Authorization': access_token,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(body)
  });

GET request fulfills and everything is fine. But the POST request is processed, but nothing is sent in response. In the browser console "Network" - Failed to load response data.
Tell me what could be the problem?
