[v8.16.1] Could not create instance of content type "SysCampaignFolder" since it has an invalid .NET class associated


I'm currently performing an upgrade from Commerce v8 to v12.5 and having just done the database update and UTC conversions, I am now running into the following issue - 

Could not create instance of content type "SysCampaignFolder" since it has an invalid .NET class associated: EPiServer.Core.CampaignFolder, EPiServer.Business.Commerce, Version=, Culture=neutral, PublicKeyToken=8fe83dea738b45b7

There is no 'SysCampaignFolder' in the DB, just a 'CampaignFolder', which may be part of the problem...?

The row for the 'CampaignFolder' is this: (forum image upload not working for me atm, will try and swap it out for a non 3rd party shortly)

Does anyone have any experience with this? I'm really struggling to find many resources on it.

The unofficial way to fix the issue is to run this SQL snippet in context of CMS database

UPDATE tblContentType
SET modelType = 'EPiServer.Core.CampaignFolder, EPiServer.Business.Commerce, Version=, Culture=neutral, PublicKeyToken=8fe83dea738b45b7'
WHERE [Name] like 'SysCampaignFolder'

Untested by me.

Hi Quan,

I had found the article that the snippet is from but was unsure whether it would be useful due to the older versions in play.

I've just ran it against the DB and it just returns the same error but with a different version number.

Could not create instance of content type "SysCampaignFolder" since it has an invalid .NET class associated: EPiServer.Core.CampaignFolder, EPiServer.Business.Commerce, Version=, Culture=neutral, PublicKeyToken=8fe83dea738b45b7

Any other ideas? Has the SysCampaignFolder been phased out in the current packages or anything like that?

Hmm, now I look into it, it looks like the content type was removed and the root was registered automatically. So can you try to back up your databases and try to delete that content type?

Hi Quan,

I deleted the content type from the database however, it seems like that results in an error -

There must still be some reference in there somewhere, are there any other tables you can think of that I'd need to check/delete some?

I think you need to delete the content in tblContent which points to that deleted content type, but it should have the reference that prevents you from deleting the content type if a content of that type still exists.

I'm not sure what to suggest you now, it's probably the time to restore the databases and contact developer support service for help .

Aug 20, 2018 11:49

Ok, I'll do that then. Thanks for your help QM.
