I am implementing a WCF based solution and all was working fine until I started to process larger quantities of data.
The Solution worked well in DEV where we added large quantities of daata when we restored the site to QA we got this error . Error rendering Councillors Online web part: [The remote server returned an error: (400) Bad Request.]
Can anyone propose a solution to this problem?
Thank you
My WCF web.config looks as follows :
========================================================
This error can also come if you WCF Code return error -- Object reference not set to an *instance of an object*
As you can track through Fiddler
{"Detail":"Object reference not set to an instance of an object."}
As you can also user Log to treas it out

All of a sudden we are seeing this random error / exception in our web application.
Failed to load resource: the server responded with a status of 502 (Bad Gateway).
In the Log Stream, we are seeing the following details, with specific error code as 502.3 - Bad Gateway: Forwarder Connection Error (ARR).
Also, sometimes in the browser itself we see "The CGI application did not return a valid set of HTTP errors." getting displayed.
Most of the searches for these error codes refer to "IIS / Proxy Server" configuration. But, we haven't changed any such settings.
The error happens very randomly and not specific to any user action/function. Same functionality works first and on second execution immediately after first one throws this error.
How to figure out what is causing this and how to fix?
I google this question, because the program was normal at the beginning, and the subsequent 502.3 error. After I checked the information on the Internet, I feel that it can only give us an inspiration, and it cannot solve your problem immediately.
So my suggestion is that first you browse post1 and post2 I provided.
Next, proceed to Troubleshoot according to the steps of the official documentation. Specific errors require specific analysis.
I'm about a month away developing my silverlight application (this is my first). Everything went rather smoothly until today, when out of the blue I started getting this message:
An error occurred while trying to make a request to URI 'http://localhost:2682/Services/Authentication/LoginService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.
I'm using WCF Services and this issue never appeared until now.
I've added a clientdomain.xml and clientaccesspolicy.xml file to my [projectname].web folder, and re-wrote them about a 1000 different ways.
I've also used Fiddler and it shows me that the error is on both those files, the error is
[Fiddler] The socket connection to localhost failed. ErrorCode: 10061. No connection could be made because the target machine actively refused it 127.0.0.1:2682
I've searched the error "10061" and it has to do with socket definition. But I couldn't find any solution to that.
Don't know if it has anything to do with it, but my "ASP.net Development Server" port is 6939.
Keep in mind that the app has NOT been deployed, so this is only happening locally. I'm using MS VS 2010 and MS SQL Server 2008.
Am I doing anything wrong or is this a silverlight issue??
On a last note, I haven't changed anything on Port, socket or service configuration. Last thing I was doing was editing a XAML file on client side and and the app started throwing me this error.
Need help, can't do anything until this is solved!!!!
Thanks.
i think you are using you app on localhost and a dynamic port is getting assigned and this port is not fixed and every run and that causes the refuse problem. if you want to fix this, create a solid url for example,
http://localhost/apps/Services/Authentication/LoginService.svc
Well, last night, just before I went to bed, I noticed something odd. In my "ServiceReferences.ClientConfig" file, the endpoint ports for each one of my services where diferent from the ones the silverlight machine used, so going on a hunch (and because I was reaching my sanity breakpoint) I decided to eliminate all my Service References and re-add them again.
I worked... go figure. Still don't know why this happened and if anyone could shed some light on the subject, I would appreciate it. It's kinda of annoying having to re-add all my services references. Right now I have only 6 of them, but in the near future they may go over 20, and if this happens again... well, it's going to be a real pain...
Thanks
So I have my web.config connection string pointing to my SQL Server on appharbor - from local (running Visual Studios) I can login and the memberships works. However from the build that is on the hosting side I get sorry, an error occurred while processing your request.
This is strange because I made a new user from local and check with SQL Server Management Studio whether or not the data has been added to the hosting server and it WORKS.
From my latest build I get the error:
Sorry, an error occurred while processing your request.
which is weird because they both point to the same server...
Anyone have an idea of what I am doing incorrectly?
ASP.NET MVC project has the "HandleErrorAttribute" on by default. You should remove it from FilterConfig.cs in App_Start Folder to see the actual error rather than the handled response.
It's located in the RegisterGlobalFilters method where filters.Add(new HandleErrorAttribute()); should be removed.
AppHarbor has a FAQ to help you troubleshoot deployment errors like these. In particular, you should inspect the "Errors" interface on AppHarbor and disable customErrors. Please elaborate the question if the FAQ doesn't help you solve the problem.
I have one user who gets the following error when trying to login, "Silverlight client load operation failed for query "Login". [GenericParameterNotValid]". The odd thing is that other users are able to login without issue and I can login using the "problem" account from other machines.
At this point I think it's got to be a client side configuration issue.
My next step is to confirm the Client Side Silverlight Version, but I don't know where to go after that.
Do you have any suggestions?
Install Silverlight Developer runtime on the client to get more details on the error.
Try deleting the user's profile.
This thread might help you.
Just leaving a breadcrumb here. We had the following error in a Silverlight RIA Services application attempting to login:
Load operation failed for query 'Login'. Error in deserializing body of the request message for the operation 'Login'. The OperationFormatter could not deserialize any information from the Message because the Message is empty (IsEmpty = true).
This was in Server 2003 with IE 8. Turns out a restart of the browser made the problem go away! Very frustrating.
Am using silverlight4.0 and using the WCF service and my functnalities are working fine and at some point of time am getting an exception as like "The remote server returned an error: NotFound." this was inner exception message and the response status code is"System.Net.HttpStatusCode.NotFound".can anyone help for this ..Thanks in advance.
The problem is that silverlight always shows not found error in many cases, the first thing that can be is that service really not available, second try to make sure that you service function is not throwing exception
Try opening the wcf service in the browser,
also this can help to investigate problem
And here is how you can configure to send real exception to client
