Requesting API leads to success on browser but status code 500 in node-red

Question

I'm trying to call an API with "http request" node in node-red (node.js).
After setting an enviroment variable "HTTP_PROXY=http://******", I could call Web pages (such as "http: //google.com") with a response of status code 200, but failed to call the API with status code 500 in node-red. I could call the API by entering URL directly on browser (Internet Explorer).
How can I solve the problem and call the API in node-red(node.js)? (what's the difference between the two means (node-red and browser))?

You have verified that the API is expecting certain headers, and throws an exception without them (ouch, bad practice!).

Anyway, to invoke the API with additional headers, you can use a change node to add them to the msg object, right before invoking the http request node:
