I did not have the issue when developing in localhost. However, once I published to a web server, the webservice was returning an empty (blank) result and I was seeing the error in my logs.

I fixed it by setting my ajax contentType to :

"application/json; charset=utf-8"

and using :

JSON.stringify()

on the object I was posting.

var postData = {data: myData};
$.ajax({
                type: "POST",
                url: "../MyService.asmx/MyMethod",
                data: JSON.stringify(postData), 
                contentType: "application/json; charset=utf-8",
                success: function (data) {
                    console.log(data);
                },
                dataType: "json"
            });

Superb   Case 2 - where the same issue can arrise  in my case the problem was due to the following line    lt webServices gt     lt protocols gt       lt remove name  Documentation   gt     lt  protocols gt   lt  webServices gt    It works well in server as calls are made directly to the webservice function - however will fail if you run the service directly from  Net in the debug environment and want to test running the function manually

In our case the problem was caused by the web service being called using the OPTIONS request method  instead of GET or POST     We still don t know why the problem suddenly appeared  The web service had been running for 5 years perfectly well over both HTTP and HTTPS  We are the only ones that consume the web service and it is always using POST   Recently we decided to make the site that host the web service SSL only  We added rewrite rules to the Web config to convert anything HTTP into HTTPS  deployed  and immediately started getting  on top of the regular GET and POST requests  OPTIONS requests  The OPTIONS requests caused the error discussed on this post   The rest of the application worked perfectly well  But we kept getting hundreds of error reports due to this problem   There are several posts  e g  this one  discussing how to handle the OPTIONS method  We went for handling the OPTIONS request directly in the  Global asax  This made the problem dissapear       protected void Application BeginRequest object sender  EventArgs e                var req   HttpContext Current Request          var resp   HttpContext Current Response           if  req HttpMethod     OPTIONS                           These headers are handling the  pre-flight  OPTIONS call sent by the browser             resp AddHeader  Access-Control-Allow-Methods    GET  POST                resp AddHeader  Access-Control-Allow-Headers    Origin  Content-Type  Accept  SOAPAction                resp AddHeader  Access-Control-Max-Age    1728000                resp End

Despite 90  of all the information I found  while trying to find a solution to this error  telling me to add the HttpGet and HttpPost to the configuration  that did not work for me    and didn t make sense to me anyway   My application is running on lots of servers  30   and I ve never had to add this configuration for any of them   Either the version of the application running under  NET 2 0 or  NET 4 0   The solution for me was to re-register ASP NET against IIS   I used the following command line to achieve this     C  Windows Microsoft NET Framework64 v4 0 30319 aspnet regiis exe -i

I also got this error with apache mod-mono  It looks like the documentation page for webservice is not implemented yet in linux  But the webservice is working despite this error  You should see it by adding  WSDL at the end of url  i e http   localhost WebService1 asmx WSDL

I was getting this error until I added  as shown in the code below    holdReady true  at the beginning of my web service call and   holdReady false  after it ends  This is jQuery thing to suspend the ready state of the page so any script within document ready function would be waiting for this  among other possible but unknown to me things      lt span class  AjaxPlaceHolder  gt  lt  span gt   lt script type  text javascript  gt    holdReady true   function GetHTML source  section       var divToBeWorkedOn     AjaxPlaceHolder       var webMethod       MyService asmx MyMethod       var parameters      source       source       section       section                ajax           type   POST           url  webMethod          data  parameters          contentType   application json  charset utf-8           dataType   json           async  true          xhrFields                withCredentials  false                    crossDomain  true          success  function data                  holdReady false               var myData   data d              if  myData    null                      divToBeWorkedOn  prepend myData html                                    error  function e                 holdReady false                 divToBeWorkedOn  html  Unavailable                        GetHTML  external    Staff Directory     lt  script gt

In html you have to enclose the call in a a form with a GET with something like   lt a href   service servicename asmx FunctionName parameter SomeValue  gt label lt  a gt    You can also use a POST with the action being the location of the web service and input the parameter via an input tag   There are also SOAP and proxy classes
