Fail to call reddit's /api/submit

Question

I couldn't get any help on reddit/r/redditdev so I'm hoping you fine folks at stackoverflow can help

I'm trying to call /api/submit.

1. I can successfully log the user in and retrieve the bearer/access token. (I use passport-reddit node module for this)
2. I can successfully call /api/needs_captcha
3. When /needs_captcha returns true, I can successfully call /api/new_captcha
4. I can display captcha image to the user

5. Now I try to call submit using nodejs' request module like so

   var options = {
     url: 'https://oauth.reddit.com/api/submit',
     method: 'POST',
     headers: {
         'Authorization': 'bearer '+usertoken
       , 'user-agent': 'node.js'
     },
     json: data
   } 
   request(options, function(error, response, body) ...
   

A sample of my "data" variable looks like this:

{ api_type: 'json',
  kind: 'self',
  sr: 'test',
  title: 'more test',
  text: 'hello world',
  iden: 'o6NsDh4IMCDb2To2DeUXJAgEPkB4O7uS',
  captcha: 'WZRTBL' }

But I get this back:

{
  "jquery":[
    [0,  1,  "call", ["body"]],
    [1,  2,  "attr", "find"],
    [2,  3,  "call", [".status"]],
    [3,  4,  "attr", "hide"],
    [4,  5,  "call", []],
    [5,  6,  "attr", "html"],
    [6,  7,  "call", [""]],
    [7,  8,  "attr", "end"],
    [8,  9,  "call", []],
    [1,  10, "attr", "captcha"],
    [10, 11, "call", ["1oWOOhcicpcpdwjENw5KrR2xHRl7J0aS"]],
    [1,  12, "attr", "find"],
    [12, 13, "call", [".error.BAD_CAPTCHA.field-captcha"]],
    [13, 14, "attr", "show"],
    [14, 15, "call", []],
    [15, 16, "attr", "text"],
    [16, 17, "call", ["care to try these again?"]],
    [17, 18, "attr", "end"],
    [18, 19, "call", []]
  ]
}

Also, I tried running this as a different user, one that has enough karma points and didn't require the captcha.

After I posted, I got this response which seems to indicate success:

{
  "jquery":[
    [0, 1, "call", ["body"]],
    [1, 2, "attr", "find"],
    [2, 3, "call", [".status"]],
    [3, 4, "attr", "hide"],
    [4, 5, "call", []],
    [5, 6, "attr", "html"],
    [6, 7, "call", [""]],
    [7, 8, "attr", "end"],
    [8, 9, "call", []]
  ]
}

But I can't find my posted message in the /r/test subreddit.

I must be doing something wrong entirely...

After going through different documentation related to /api/submit, I have discovered that you have missed the field uh of your sample of "data". Missing of uh entails to errors that look like yours (look documentation below)

Here more documentation related what I said:
