It looks like there is something missing in the node that you were viewing. Probably it could find the node's MetaClass Id. You might want to check the CatalogNode and MetaClass tables.

You can check and show us procedure [ecfVersion_ListByWorkIds] in ECF database

<p>I have figured it out!</p>
<p>Just before failing following is called:</p>
<pre class="brush:sql;auto-links:false;toolbar:false" contenteditable="false">exec mdpsp_sys_LoadMetaClassById @MetaClassId=32</pre>
<p><br />it returns empty result as that metaclass does not exist anymore(for 4 years now) in MetaClass table</p>
<p>So then when method StartDate is called:</p>
<pre class="brush:csharp;auto-links:false;toolbar:false" contenteditable="false">private static DateTime StartDate(this CatalogNodeDto.CatalogNodeRow catalogNodeRow, MetaDataContext context)
{
if (catalogNodeRow == null)
{
return DateTime.MinValue;
}
MetaObject obj2 = MetaObject.Load(context, catalogNodeRow.CatalogNodeId, catalogNodeRow.MetaClassId) ?? new MetaObject(MetaClass.Load(context, catalogNodeRow.MetaClassId), catalogNodeRow.CatalogNodeId);
DateTime? nullable = null;
if (obj2 != null)
{
DateTime? nullable2 = nullable = (DateTime?) obj2["Epi_StartPublish"];
if (nullable2.HasValue)
{
return nullable.Value;
}
}
return catalogNodeRow.StartDate;
}</pre>
<p><br />it tries to load:</p>
<pre class="brush:csharp;auto-links:false;toolbar:false" contenteditable="false">MetaClass.Load(context, catalogNodeRow.MetaClassId)</pre>
<p><br />witch returns null, becasue obviously metaclass with id 32 is not present in database</p>
<p>then it tries to new up MetaObject and that null is passed in and everything fails</p>
<p>checked my database by running query:</p>
<pre class="brush:sql;auto-links:false;toolbar:false" contenteditable="false">SELECT MetaClassId, count(*)
FROM [dbo].[CatalogNode]
GROUP BY MetaClassId</pre>
<p>result:</p>
<pre class="brush:plain;auto-links:false;toolbar:false" contenteditable="false">MetaClassId (No column name)
32 1
33 1037</pre>
<p><br />that one catalog node with id 32 is from 2012, and is old test category that was forgotten -> so i deleted it</p>
<p><br />Afterwards it works without errors!</p>
<p><br />Weird thing is it was in diferent catalog than I was looking at, so i think it should not have affected other catalogs(however i have products underneeth there that are in other clalogs/catalog nodes as well), it is hard to say if it would have been better that commerce just eats that one category and shows everything else than nothing, but still:</p>
<p>To repeat this, go to your CatalogNode table change one of the rows MetaClassId to non existant metaclass and commerce catalog browser will have problems</p>

This topic was created over six months ago and has been resolved. If you have a similar question, please create a new topic and refer to this one.
This problem is supposed to be fixed by this: http://world.episerver.com/documentation/Release-Notes/ReleaseNote/?releaseNoteId=COM-551
What have I done is:
Upgraded Commerce from 7.12.0 to 9.7.0
Migration seems to finish successfully, but afterwards in following screen -
http://site/cms/Commerce/Catalog#viewsetting=viewlanguage:///nb-NO&context=epi.cms.contentdata:///1073742019__CatalogContent
What else could be wrong?
What more details are needed to figure this out?
