Answer 1

I seems that you are using express.js. I believe that your problem is, that body is actually already parsed. You can check it by reading req.body. The situation is caused because express.js already read whole body (due to the content type) and trying to read body again will cause timeout (event data and event end are not emitted). There are several ways how to fix it.

1. disable express.js body parser - or reconfigure it to ignore json

2. remove reading body code and use directly req.body

app.post("/api/bats_push",(req, res) => {
        //console.log("Calling bats_push...")
        const d = {
            method: req.method,
            headers: req.headers,
            query: req.query,
            body: req.body
        }

        DATA.push(d);
        res.end('Saved BATS job details');
});
