HPE_UNEXPECTED_CONTENT_LENGTH : Content-Length can't be present with Transfer-Encoding

[54NK37]

How to resolve this issue ?

• I am using createProxyMiddleware({target: this.url, changeOrigin: true, ws: true, timeout: 6000000, secure: false});
• Somewhere compression is happening inside middleware which is adding Transfer-Encoding header I guess. I am not explicitly adding any compression middleware on express app.
• I tried removing header from onProxyRes but it didn't work.
  onProxyRes : responseInterceptor( res.removeHeader('Content-Length'); OR delete proxyRes.headers['transfer-encoding']; OR res.removeHeader('Transfer-Encoding'); )
• My target is getting partially loaded but with broken css and it keeps on retrying with same error for each request.
• Example of request and response headers without proxying
