Content Tree Not Showing
I haven't seen this error myself, but how about decompiling Epi and see what it does with GetChildren and kind of loaderoptions are created in Episerver/CMS/stores/contentstructure?
guess you could find inspiration to create something that does getchildren to recreate the issue in your own code that you can debug.
another tip is to use the browser built in developer tools, the console and network functions can easier let you see what traffic EPiServer is using so that you don't need to switch back and forth between browser and fiddler. Even if Fiddler usually is a great tool! :)

Alf, thank you for your response. I was able to resolve the issue and get the Content Tree to appear. Steps to resolve the issue are below:
First I tried to get all the children from the root using the following statement
var children = DataFactory.Instance.GetChildren(ContentReference.RootPage);
This threw the same error as mentioned in my post above.
So, I then used the GetDescendents to get a listing of all the Page References and then looped through those Page References performing a GetPage on each one:
var descendentLinks = DataFactory.Instance.GetDescendents(ContentReference.RootPage);
foreach (var link in descendentLinks)
{
Debug.WriteLine(link.ID);
try
{
var descendent = DataFactory.Instance.GetPage(link, LanguageSelector.AutoDetect(true));
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
}
}
In my output I received an error regarding content ID 147 that it did not contain a Language entry in the tblContentLanguage table. Once I added a row in the tblContentLanguage table for that Content ID, the Content Tree rendered.

Recently, the Content Tree in the left pane is not appearing in our Epi 9.9 project. The Root name and Icon appear, but the three blue bars to the left of the name continuously cycle and the tree will not appear. Looking in Fiddler I noticed there was a 500 error when trying to load the following url
/EPiServer/cms/Stores/contentstructure/?referenceId=1&query=getchildren&typeIdentifiers=episerver.core.pagedata&allLanguages=true&sort()&dojo.preventCache=1464715414299
I copied the url into a new browser tab and was able to see the following error:
The given key was not present in the dictionary.

We've checked all Block Types and Content Types on the Admin > Content Type tab and there is no missing properties. I've also checked in the database and verified all the content types exist in the database. Is there a way to determine what content, page type or property could be throwing this error?
Thanks in advance!
