Hi Richard.

Thanks for replying.

On this site we do not run any background process. And we do not get any visual errors when trying to edit in backoffice. But it shows up in the log files.

Could it have anything to do with it running in trial mode?

We had a trial license on and changed it to a real one, but we still have the same issue.

We are trying to find out when the problem occours, but we cant seem to trigger it, it just shows up in the log.

When i view a document in Umbraco that uses SeoChecker, then i get this Error 3 times in a row: When i save the document i get the same error again 2 times in a row.

System.ArgumentNullException: Value cannot be null.
Parameternavn: Cannot find a content type  with alias 
   ved SEOChecker.Core.Repository.Definition.DefinitionFactory.Single(String alias)
   ved SEOChecker.Core.Config.Configuration.GetDocumentTypeByAlias(String alias, String doctypeAlias)
   ved SEOChecker.Core.Config.Configuration.GetDocumentTypeByAlias(String alias)
   ved SEOChecker.Core.Umbraco.DocumentWrappers.UmbracoDocument.get_SEOConfiguration()
   ved SEOChecker.Core.Extensions.UmbracoDocumentExtensions.GetDefaultTitlePropertyValue(IUmbracoDocument doc, String culture, String segment)
   ved SEOChecker.DataTypes.Model.SEOCheckerModel..ctor(SEOCheckerValues value, IUmbracoDocument document, SEOCheckerDataTypeConfig datatypeConfig, String culture, String segment)
   ved SEOChecker.DataTypes.PropertyEditors.PropertyEditorWrappers.SEOCheckerPropertyWrapper.ToEditor(Property property, IDataTypeService dataTypeService, String culture, String segment)

As a bonus info. The document i tried this on was not published, only saved.

When i try to do a schedule publish i get this debug info, that leads to a 404 error.

SEOChecker: SEOChecker: SEOChecker httpmodule called for uri http://localhost:7579/umbraco/backoffice/UmbracoApi/Content/PostSave

Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:7579/umbraco/backoffice/UmbracoApi/Content/PostSave

Ok the last is not a SEO Checker error and great find Now I can reproduce as well. Will fix ASAP. Was better to have a new topic by the way since this was related to a total different issue.

Best,

Richard

I should maybe have created a new topic. But i did not want to have 2 unfinished topics with the same name.

But great that you can reproduce, so you can try fix it.

Yes the last is only a debug info. But i was wondering why SeoChecker is calling http://localhost:7579/umbraco/backoffice/UmbracoApi/Content/PostSave when i try to do a schedule publish?

Hi Richard.

When you have a fix for it, please post it, then i mark it as the correct answer :)

I will create a new bug report for the debug info from the SEOChecker.Core.Components.UrlRedirectComponent.

Hi Thomas,

Use this hotfix please.

Hope this helps,

Different Image type maybe? The picker checks the datatype to determine if something is a picker.

hmm have tried with the same image on diffrent doctype. It only works on one of them..

Also, I have added the hotfix. still getting the log error:

"SEOChecker: SEOChecker: Error converting DB values to editor values"

Only on the item that is not having the image picker I assume? Any other errors related to this in the log?

Both doctypes have the same composition.

With the same Image picker / alias.

In Seochecker both doctype in social have the same picker..

"SEOChecker: SEOChecker: Error converting DB values to editor values"

System.NullReferenceException: The object reference is not set to an instance of an object. by SEOChecker.Library.MetaData..ctor (Int32 id, String culture, String segment) by SEOChecker.DataTypes.Model.SEOCheckerSocialModel..ctor (SEOCheckerSocialValues ​​value, IUmbracoDocument document, SEOCheckerSocialDataTypeConfig Statring.DonTypeConfig datatypeConfig .PropertyEditors.PropertyEditorWrappers.SEOCheckerSocialPropertyEditorWrapper.ToEditor (Property property, IDataTypeService dataTypeService, String culture, String segment)

Ah ok, That si almost the same error but on a different property editor. Makes sense now. This one was on the list to fix but need some time to check it. Seems that something is accessing the property editor without httpcontext. Will come back to this but is a nasty one to fix,

Cool :) Thanks

I Think there is an issues with Umbraco Cloud and the HttppContext to, mayeb they do something on a background thread that causes this on Cloud.

Looking at the lines where the exception is thrown:

IPublishedContent publishedContent = ContextHelper.UmbracoHelper.Content(id);
this._document = ((publishedContent.Id == 0) ? new UmbracoDocument(id, new ContextInfo(HttpContext.Current), culture, segment) : new UmbracoDocument(publishedContent, new ContextInfo(HttpContext.Current), culture, segment));

It wouldn't hurt adding simple null checks for ContextHelper.UmbracoHelper and publishedContent, right? I guess one of those is null.
