What http-proxy-middleware configuration are you using?

module.exports = function(app) {
 var restream = function(proxyReq, req, res, options) {
   if (req.body) {
       let bodyData = JSON.stringify(req.body);
       proxyReq.setHeader('Content-Type','application/json');
       proxyReq.setHeader('Content-Length', Buffer.byteLength(bodyData));
       proxyReq.write(bodyData)
       proxyReq.end();
   }
 }
 
 app.use(bodyParser.json());
 app.use(bodyParser.urlencoded());
 app.use(
   '/api/*',
   createProxyMiddleware({
     target: 'https://<domain>/',
     changeOrigin: true,
     pathRewrite: {
       '^/api/': '<path>'
     },
     logLevel:'debug',
     onProxyReq: restream,  
   })

};

Did you try the fixRequestBody instead of your own restream?

const { createProxyMiddleware, fixRequestBody } = require('http-proxy-middleware');

const proxy = createProxyMiddleware({
  /**
   * Fix bodyParser
   **/
  onProxyReq: fixRequestBody,
});
