I'm trying to publish a new .NET web app to our development environment version 9.1.608.0

I'm getting this error which none of our other developers have seen:

Hey JX,

can you show the Error Log from Service Center?



I was able to resolve this error.  Apparently, a single column identity table is not allowed.  Once I added a second column, the error was resolved.
