I have noticed some Jquery.min.map 404 errors in the chrome console. When I try to go to one of the lines that has the problem, it refers to a ScriptReserouce that contains a "Telerik.Web"UI" reference.

Is there something that should be turned on or off to prevent these errors. I am using Q1 2013.

I am also seeing this errors, but the stack overflow article talks about jquery 10.1, and I have been using the kendo supplied 1.9.1.

Will I get into issues, by increasing the jquery version?

Hi guys,

The problem is related with the Chrome devtools, which have an option named "Enable source maps". When turned to on it will search for map files for the common JS libraries. You can take a look at the intro video for more information at the topic. In general, you can either disable the source maps or place source map files in your projects.

I see the source maps for 10.1.2, http://jquery.com/download/

Kendo is shipping with 1.9 is it safe to upgrade JQUERY and use the newer source maps?

Hi,

In general it is best to use the jQuery version that comes with the current version of the controls because it is the one that is tested and stable.

Hi Asar,

Please disable the "Enable source maps" feature from the chrome dev toolbar. More information on how to do that can be found in the following StackOverflow thread -> http://stackoverflow.com/questions/18365315/jquerys-jquery-1-10-2-min-map-is-triggering-a-404-not-found

I recently started to get those message as well. I get them on both Chrome and Firefox dev toolbar :

SyntaxError: Using //@ to indicate source map URL pragmas is deprecated. Use //# instead @ http://localhost:49573/Telerik.Web.UI.WebResource.axd

I set up my web site to shoot me an email as well each time it throws an error and here's what I get :

An Error Has Occurred!

URL:	/jquery.min.map
User:	melmmt
Exception Type:	System.Web.HttpException
Message:	File does not exist.
Stack Trace:	at System.Web.StaticFileHandler.GetFileInfo(String virtualPathWithPathInfo, String physicalPath, HttpResponse response) at System.Web.StaticFileHandler.ProcessRequestInternal(HttpContext context) at System.Web.DefaultHttpHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Is this REALLY related to the dev toolbar ? If so, how come IIS sends me this ?
Also, it might not be related but this is something I have noticed at the same time this error appeared, my login ASP Panel with a default button doesn't do anything when I press the Enter key. It's pretty straight forward though :

<asp:Panel ID="panel" runat="server" DefaultButton="rbtSubmit">

<telerik:RadTextBox ID="rtbUsername" runat="server" TextMode="SingleLine" Label="Username:" EnableSingleInputRendering="true" CssClass="riTextBox" MaxLength="32"></telerik:RadTextBox>

<telerik:RadTextBox ID="rtbPassword" runat="server" TextMode="Password" Label="Password:" EnableSingleInputRendering="true" CssClass="riTextBox" MaxLength="12"></telerik:RadTextBox>

<telerik:RadButton ID="rbtSubmit" runat="server" Text="Login" Icon-PrimaryIconCssClass="rbOk" Width="100" OnClick="rbtSubmit_Click" CausesValidation="true"></telerik:RadButton>

</asp:Panel>

I did this with Q2 2013 and still does with Q3.

Cheers,

Chris

Hello,

The error that you receive from IIS is notifying you that IIS cannot fine a file named jquery.min.map to ship to the client. It is not a real error with IIS but a simple notification of missing resource. Indeed, the reason for this is that Google Chrome requests the map file automatically and it requires explicit turn off in order to stop.

So basically Telerik is ok with shipping an embedded script that will cause 404 requests on every page that uses one of your controls. And your advice is to pass on instructions on how to disable a option that is enabled by default in both Chrome and Firefox to all of our customers?

Seems like a better approach would be for you guys to remove the sourceMapping comment in the embedded script. Just sayin.

Hello Adam,

Thank you for the good suggestion, I've updated your Telerik points as a token of gratitude.

It is likely that for our next service pack we will have the sourcemap redirected to a valid source map URL and provide an option to disable it altogether.
