Hi Paul,

as this is a new installation I hope you don't mind if I ask if you completed all setup steps described here:

https://help.nintex.com/en-US/nintex2016/current/#sp2016/InstallGuide/InstallProd.htm 

Especially Database setup might be important here.

Can you create and publish site workflows or do you also get errors there?

Also ULS log might give you more detail what is expecting the column in question and where it looks it up.

Best regards

Enrico

Enrico,

No such luck.  I went through the Guide and did everything and still getting this issue.

Hmm, maybe something wen't wrong during installation. I couldn't find anything useful related to this error message so I think it's best to reach out to Nintex support and have them have a look on your installation and environment.

Best regards

Enrico

I think it may have something to do with our SharePoint Installation.  I tried it on a Site Collection that is "Path-Based" and it works fine.  But most of our Site Collections are "Host-Named".  And that is where its failing to save or publish with the following ULS entry.

System.ArgumentException: urlOfFile  Parameter name: Specified value is not supported for the urlOfFile parameter.
