Put request throws error with headers option

[keller35]

I got an error from a PUT request.But i found it can work without the header option.
The request with a header options is like this:

'use strict';
var request = require("request");

request({
  method: 'PUT',
  uri: 'http://v2.openapi.ele.me/restaurant/62028381/order_mode/?consumer_key=0170804777&sig=bc8b56be4f9d33942eb22bd66ab1f2a49eea91f4&timestamp=1465890208',
  body: {
    order_mode: 1
  },
  json: true,
  headers: {
    "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8"
  },
}, (err, response, body) => {
  console.log(body);
});

And the error is:

/Users/keller/xfxb/brownie/node_modules/request/lib/querystring.js:44
  return str.replace(/[!'()*]/g, function (c) {
             ^

TypeError: str.replace is not a function
    at Querystring.rfc3986 (/Users/keller/xfxb/brownie/node_modules/request/lib/querystring.js:44:14)
    at Request.json (/Users/keller/xfxb/brownie/node_modules/request/request.js:1201:30)
    at Request.init (/Users/keller/xfxb/brownie/node_modules/request/request.js:421:10)

    at request (/Users/keller/xfxb/brownie/node_modules/request/index.js:55:10)

Is there any problem with my headers option or is the problem from the module?

Try form instead of body

form: {
  order_mode: 1
},

I get the same error. its trying to string.replace on an object, when using Body, but the headers is set to FormData. So its a mixup of data types

set 'useQuerystring': false in reqOptions:

'use strict';
var request = require("request");

request({
method: 'PUT',
uri: 'http://v2.openapi.ele.me/restaurant/62028381/order_mode/?consumer_key=0170804777&sig=bc8b56be4f9d33942eb22bd66ab1f2a49eea91f4&timestamp=1465890208',
body: {
order_mode: 1
},
json: true,
useQuerystring: false,
headers: {
"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8"
},
}, (err, response, body) => {
console.log(body);
});
