Solved: The length of the URL for this request exceeds the configured maxUrlLength value.

Jared Meredith

Anyone ever run into the following before? I ran into this regarding a request into the SharePoint Rest API.

The length of the URL for this request exceeds the configured maxUrlLength value.

This because the IIS default maximum length for an URL is 260 characters. If a URL request is longer, the above error will occur.

To fix this you can increase the maxURLlength value, add it to your web.config file in the IIS virtual Directory.

<configuration>

  <system.web>

    <httpRuntime maxUrlLength="5000" />

  </system.web>

</configuration>

It will be likely you will already have most of this snippet in place so don’t break your config; just add the maxUrlLength property into your existing httpRuntime section and you should be good to go. Do know any web.config changes may cause a service interruption so test in dev, beta, QA and pre-prod before ever changing in prod! Hope this helps, questions are welcome!

Solved: Method not found: ‘!!0[] System.Array.Empty()’.

If you are getting a message for your recently developed .Net application when you publish to the server to the effect of:

ssnetframeworkerror

Chances are the server you are deploying to does not have the appropriate framework to support your app.

Download the Microsoft .Net Framework 4.6.1 and install it to resolve this. It will likely require a server reboot to complete it so don’t do it on prod mid-day! Hope this helps, questions are welcome!

Troubleshooting “Could not load file or assembly ‘DotNetOpenAuth.Core, Version=4.1.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246’ or one of its dependencies”

Jared Meredith

The Issue:

After I had updated my .Net Core on my developer machine to a newer version I went to debug a web application I had and received this error:

Could not load file or assembly 'DotNetOpenAuth.Core, Version=4.1.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The Problem:

Here is what I had in my config prior to the update install:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="DotNetOpenAuth.Core" publicKeyToken="2780ccd10d57b246" />
        <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.1.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="DotNetOpenAuth.AspNet" publicKeyToken="2780ccd10d57b246" />
        <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.1.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

I had outdated references in my config file.

The Solution:

Ensure your references get updated after you update your development environment.

Here is what I updated to:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="DotNetOpenAuth.AspNet" publicKeyToken="2780ccd10d57b246" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="DotNetOpenAuth.Core" publicKeyToken="2780ccd10d57b246" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

Hope that helps. Questions are always welcome.

Help! Need Help Diagnosing A 500 Errors In SharePoint? Try This…

Jared Meredith

Imagine the nightmare…you decided to sneak in a web part deployment in right before the start of the business day. Right after your deployment you see that the site is about to come back up…and…then nothing. A blank screen. In desperation you open Internet Explorer to try and see if it loads there as well..nothing but a 500 error. Then, the feeling rushes over you that this was a very bad decision. While we should address why you were doing an early morning deployment we shall spare you. 🙂 So what do you do now?

One of the best ways to see what is going on with a 500 error is to enabled Failed Request Tracing in IIS for the web site in question. Once enabled you can replicate the issue by refreshing the browser a few times; this should be more than enough to capture a few. Once captured then you will usually see where the issue is identified (especially with web.config changes that happen).

To do this:

1) Open IIS

2) Select the web site in question and open the Features View

3) Under the IIS section select “Failed Request Tracing” by double-clicking it

FRT1

4) In the top right hand corner click the message in the Alerts section

FRT2

5) When the pop-up comes up then select to enable and take the default directory (unless you need it elsewhere, then specify another location) and hit OK

FR3

6) Next, under actions select “Add…” and select “All content (*)” and click Next

FRT4

7) Indicate the status code of 500 (and others where applicable) and click next again

Frt5

8) Indicate your trace providers and click Finish

FRT6

You should now see your created Failed Request Tracing Rules.

FRT7

Now go and refresh the browser a couple times to see your error again. Once that is logged then go to the trace logs. To find that location go back to the site in features view, select Failed Request Tracing and select “View Trace Logs…”

FR8

Double click to view the recorded log (you can use IE):

FRT9

Viewing these should at least help to identify the obvious when it is a line in the web.config or when there has been a setting changed as a result of saving a configuration option in SharePoint (or 3rd party products or web parts in SharePoint). Hope this helps, happy troubleshooting. Questions are always welcome.

 

Sitecore, Sitecore Rocks, Troubleshooting, Visual Studio

Getting “Error: this template attempted to load component assembly Sitecore.Rocks.TemplateWizard…” ? Try this…

Jared Meredith

At some point in your early Sitecore career you will likely encounter the following error:

sitecorerockserror

Perhaps you tried uninstalling and reinstalling Sitecore Rocks but still had the issue? Here’s what happened in my battle with troubleshooting.

So I finally went and found the Sitecore.Rocks.TemplateWizard.dll and copied it to:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PublicAssemblies

If you have trouble finding where those assemblies are then look where the extension was installed. For me it was starting here

C:\Users\username\AppData\Local\Microsoft\VisualStudio\12.0\Extensions

Once there I browsed the directories until I found it.

(Others I know have had to copy to Visual Studio 10 and 11 as well)

These steps did fix the issue and allowed the template wizard to run when creating a layout.

If you are still receiving other errors after this you may need to also bring in some other files. What was missing was a good number of other dlls:

  • Sitecore.Rocks.Validation.dll
  • Sitecore.Rocks.Validation.Runner.config.xml
  • Sitecore.Rocks.Validation.Runner.exe
  • Sitecore.Rocks.Validation.Runner.exe.config
  • Sitecore.Rocks.VisualStudio.dll
  • Sitecore.Rocks.VisualStudio.pkgdef
  • (and of course Sitecore.Rocks.TemplateWizard.dll)

After copying these out to the folder mentioned above and restarting Visual Studio, my issue was resolved. Hope that helps.
