Create User from Node.js Failure.

nodebb version 1.13.2
nodebb-plugin-write-api version 5.7.3
node.js version 12.14.1

post data:
username=Panama.City&password=12345678&email=panama.city%40domain.com

http request option:

{ hostname: 'localhost',
  port: 4567,
  path: '/api/v2/users',
  method: 'POST',
  timeout: 5000,
  headers:
   { Authorization: 'Bearer <token>' } }

var req = require('http').request(options, (res) => {
   							
   	 let data = '';

   	 // A chunk of data has been recieved.
   	 res.on('data', (chunk) => {
   		data += chunk;
   	 });

   	// The whole response has been received. Print out the result.
   	res.on('end', () => {
   					
   		console.log(data);
   		var rt = JSON.parse(data);
   		if (callback) callback({status: 'success'});
   					
   	 });
   				  
   	 req.on('error', (e) => {
   					  
   		if (callback) callback({status: 'failure'});
   					
   	 });	
   });
   							
   req.write(postData);
   req.end();

Error: "value" required in setHeader("accessToken", value)
    at validateHeader (_http_outgoing.js:492:11)
    at ClientRequest.setHeader (_http_outgoing.js:501:3)
    at new ClientRequest (_http_client.js:173:14)
    at Object.request (http.js:38:10)

Any idea what I did wrong there? Thank you for an excellent plugin to an excellent forum platform.

Start by reproducing the POST request to the /api/v2/users entry point with the versions and request options shown. Inspect how the write API handles the Authorization header and accessToken during user creation, then compare that path with the reported setHeader error. Done means the request either creates the user successfully or returns a clear, documented API error.
