I have a node.js API as below to which I send a POST request from python as below,the issue am facing is if I remove the headers={"Content-Type": "application/json"} the POST goes thorugh,if not i get a Read timed out. error, can anyone provide guidance on how to fix this timeout error ?

node.js endpoint

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.on('data', (c) => {
            //console.log(c)
            d.body = d.body + c
        });

        req.on('end', () => {
            DATA.push(d);
            res.end('Saved BATS job details');
            //res.status(200).json({
              //message: "Saved BATS job details",
              //posts: req.body
          //}); 
        });
});
