Response is missing a body

[marians]

Hi! I am getting a request through to searchkit-express, but the response contains no body. When I issue requests directly against ElasticSearch, things work as expected.

Here is my server:

var express = require('express');
var SearchkitExpress = require("searchkit-express")
var cors = require('cors');
var morgan = require('morgan')
var jwt = require('express-jwt');
var jwks = require('jwks-rsa');

var app = express()

var host = process.env.ELASTICSEARCH_URL || 'http://127.0.0.1:9200';
var port = process.env.PORT || 8080;
var index = process.env.ELASTICSEARCH_INDEX || 'documents';

var jwtCheck = jwt({
    secret: jwks.expressJwtSecret({
        cache: true,
        rateLimit: true,
        jwksRequestsPerMinute: 5,
        jwksUri: 'https://some-subdomain.auth0.com/.well-known/jwks.json'
  }),
  audience: 'my-audience-string>',
  issuer: 'https://some-subdomain.auth0.com/',
  algorithms: ['RS256']
});

app.use(morgan('combined'));
app.use(cors());
app.use(jwtCheck);

app.listen(port);

SearchkitExpress({
  host: host,
  index: index,
  queryProcessor: function(query, req, res) {
    if (req.method !== 'POST') {
      return null;
    }

    return query
  }
 }, app);

NodeJS version: v12.12.0

The request body is supposed to be empty, as I am trying to retrieve all documents.

Any suggestion what I could do to debug the situation?

Thank you!

Found it. I missed the part using bodyParser from the README. body-parser has become a dependency to be installed and imported.

var bodyParser = require('body-parser');

...

app.use(bodyParser.json());

Seems to work.
