Thingsboard I/O error on POST request

I'm trying to create a plugin that posts the data it receives from devices to another application. However, I don't see any data coming in on my application. When I look at the plugin's error events I see the following stack trace: 

org.thingsboard.server.extensions.api.rules.RuleException: I/O error on POST request for "http://127.0.0.1:7890/stream/gps":
Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused)

I've quickly set up a node server to test if the data is being sent.

const express = require('express');
const app = express();
const cors = require('cors');
const bodyParser = require('body-parser');
app.use(cors());
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());
app.all('*', (req, res, next) => {
    console.log('received request');
    next();
});
app.get('/', (req, res, next) => {
    res.status(200).send('It works');
    next();
});
app.post('/stream/gps', (req, res, next) => {
    console.log(req.body);
    res.status(200).json(req.body);
    next();
});
app.listen(7890, () => {
    console.log('Server listening on port 7890');
});

and when I do a post with insomnia or postman to the url, I get a 200 success

Found the problem, running the Thingsboard inside a docker container, so localhost === container localhost, not my device where I run the node server
