$.ajax call returns application/json and works on test server, text/html on production server and fails

Foreword: I know there are many questions similar to this, but none of them have helped me.

I'm in a bit of a bind.

I have an ASP.NET application that uses an $.ajax call to return some data to the page. I have this on 3 different application servers, all of which are Windows Server 2003.

I am NOT running this locally, it is on 3 web application servers. 2 work, 1 doesn't.

This call works flawlessly on the Dev server, the DevTest server, but fails on the production server. I checked the console in Chrome and found that in my Dev and DevTest environments, the ajax call is returning application/json, but on production is returning text/html. Also, on my Dev and DevTest servers, everything works as it should and I get the json returned as it should, but on production, I get a 200 OK, but it returns the entire calling pages html and executes the error function of my ajax call.

Here is my ajax call:

$.ajax({
      type: "POST",
      contentType: "application/json; charset=utf-8",
      url: "RequestDetail.aspx/postAsync",
      data: "{'reqSystem': '" + $('#ctl00_PlaceHolderMain_lblRequestSystem').text() + "', 'vendorNumber': '" + $('#ctl00_PlaceHolderMain_txtVendorNo').val() + "'}",
      dataType: "json",
      success: AjaxSucceeded,
      error: AjaxFailed
      });

Here is the code behind:

<System.Web.Services.WebMethod()> _
Public Shared Function postAsync(ByVal reqSystem As String, ByVal vendorNumber As String) As String
    Dim required = CheckForSpecialApproval(reqSystem, vendorNumber)
    Return required.ToString()
End Function

Here is what I'm seeing in my console in Chrome on production:

Production Chrome Console

And This is what is looks like on Dev:

Dev Chrome Console

I checked the mime types in IIS on my production server and the mime types for javascript and json didn't exist so I had to create them, but it still isn't working. I Googled this to no end and I can't figure out what the problem is.

If you need any other information, I'll gladly provide it.

Please Help.

Thanks in advance.

Turns out there were missing entries on the production web.config:

Thanks everyone for your time and answers.

The production responses are all strangely identical in size and much larger than the dev response (173KB against 366B). You should investigate the content of that text/html response - it is very possible that the content is actually an error message formatted in HTML. If Chrome does not give you the ability to view the response, use Fiddler.
