Problems when indexing after upgrade

Hi,

I did some software upgrades for our customer the other day, everything seemed to work fine, but when I try to re-index stuff, no pages will be indexed, instead I got loads of errors ( in the logs ), this happens both when the "EPiServer Find Content Indexing Job" and when I for ex publish a page.

Nothing is changed in the code, except for new software versions.

Parts of packages.config ( now, after upgrade )

Parts of the Errors from logs ( this is when I try to publish/Index even my simplest "ContainerPage", code for that one below ), I remove stuff that's just reapeated

{
public override void SetDefaultValues(ContentType contentType)
{
base.SetDefaultValues(contentType);
VisibleInMenu = false;
}
}

Also, in a InitModule, I tried to add handling for ReferenceLoopHandling ( did not need that before upgrade ), but that did not help either

    [InitializableModule]
    [ModuleDependency(typeof(FrameworkInitialization))]
    public class WebApiInitialization : IInitializableModule
    {
        public void Initialize(InitializationEngine context)
        {
            // Enable Web API routing
            GlobalConfiguration.Configure(config =>
            {
...
                var settings = jsonFormatter.SerializerSettings;
                settings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; // added this line, but it did not helt
...

Will be very happy if you have any ideas on how to solve this :)

Are you using NestedConventions? Have a look at this?

Hi,

I can't find the word "NestedConventions" in my source code, also it seems like the post you are referring to is about searching, not indexing, but thanx anyway :)

I would try:

Add the attribute [JsonIgnore] to all properties on ContainerPage.
Check if indexing work.
If indexing works, try removing the attributes one by one, until you can pinpoint what property causes the issues.

Example:

[JsonIgnore]
public string SuspectProperty { get; set; }

Hi,

The problem is that it's not even possible to index this class ( without custom properties ):

[ContentType(DisplayName = "RAVerySimplePage", GUID = "EB44C08C-F8BC-4586-A594-26DF166C5B8E")]
public class AVerySimplePage : PageData
{
}

Same errors

Were you ever able to get this resolved? I'm getting the same error:

Self referencing loop detected for property 'ManifestModule' with type 'System.Reflection.RuntimeModule'

with Episerver 11.20.17 + Find 13.5.2. Downgrading Find to 13.0.5 gets rid of the error, but comes with a set of dependencies that won't work except for just trying out stuff locally...
