FatalError: Object reference not set to an instance of an object...at...ContentTypeSerializer.GetContentType

Sep 14, 2009 at 7:09 PM

I'm trying to run an import on a handful of document libraries, but get a similar error message for each one.  It is possible that I'm using the wrong parameters in the import wizard.  Here's a list of the parameters followed by the error.

Action:  Import

Sharepoint site:

       Site URL:  http://intranet/projects/archive2

      Import web URL:  http://intranet/projects/archive2

Import type:

     From single file

     Retain object IDs (unchecked)

     Include Security:  All

     Version options:  Append

     User info update:  Import All

Hi Jeff

Try again with the "Retain Object Ids" box checked.

I get a similar error to the one above when trying to import a handful of site collections. I can export and import some of the site collections individually but not the main site.
If I try to import only the main site it refers to a dependency to a site collection of WIKI type so I include that site in the export.
But then I get this error when importing:
I tried with retain Object ID's checked without any difference.
Any clue of where I shall start looking for the origin of the error?
Thank in advance

Hey, your problem is (probably) caused by wrong filled "Import web URL" field.
