    6.2.2 InternalIndexer error ArgumentNullException: Parameter name: contentType

    I upgraded from 4.11 to 6.2.2. Everything works on my site but I am unable to run the indexer. The Developer section of the backoffice is really slow because it attempts to index every time I go to that section. Whenever I run the Rebuild tool from the Examine dashboard it fails with the error below. I have checked in my database in tables like cmsContent and cmsContentType but see nowhere where this value could be null.

    error: The index could not be rebuilt at this time, most likely there is another thread currently writing to the index. Error: System.ArgumentNullException: Value cannot be null.

    In the examine settings I tried to set supportUnpublished="false" which allowed my InternalIndexer to complete. However, my InternalMemberIndexer still does not index correctly even though it runs to completion

    <add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
           supportUnpublished="false"
           supportProtected="true"
           interval="10"
           analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"/>

    Hmmm do you have any media that is null in the content tree?

    Thanks for the hint, Charles. In my case, I had almost the exact same error as Jim, except my stack trace referenced the mediaRepository instead of the contentRepository. Sure enough, I found some media in the root of my media tree that had no icon. I clicked it and saw YSODs that said:

    Value cannot be null. Parameter name: contentType.

    It looks like sometime in the site's past, the media type associated with these media items was deleted. I am unable to delete these offending media nodes from the umbraco backoffice, so I had to manually delete them with SQL

    DELETE
FROM cmsContent
WHERE nodeId = 3400 OR nodeId = 3512

DELETE
FROM umbracoNode
WHERE id = 3400 OR id = 3512

    I ran an additional query to find any other nodes without contentTypes. I found a bunch more, but left them alone because they aren't causing any problems. They are all nodes in the content tree. Looks like umbraco only freaks out if the media lack a contentType.

    SELECT TOP 1000 *
FROM umbracoNode n
INNER JOIN cmsContent c
   ON c.nodeId = n.id
WHERE c.contentType = 0

    No worries mark, a I guy I used to work with had the problem when we were importing media and they became null. When We tried to index we got exceptions. Speaking of SQL I thought the was a script knocking around that would clean any duplications or corrupt nodes.

    The one above with almost certainly be a doc type that has been removed or has duplicated fields perhaps or is just null.

    Thanks for the SQL, that rocks :). I will try and see if I can find the script it might help as well. Charlie.

    This information saved me today - thank you all!

    One thing - I had to add an additional first SQL statement for it to run correctly:

    DELETE
FROM cmsContentVersion
WHERE ContentId = 23222

DELETE
FROM cmsContent
WHERE nodeId = 23222

DELETE
FROM umbracoNode
WHERE id = 23222
