Commented Unassigned: Script halt when creating new content database [20868]

I mistakenly posted this in the Issues section earlier, but I'm not looking for support here. My script ran through all the way to creating a new content database, and I got this output:

Creating new content database "PROD_MySiteHost"...
Get-SPWebApplication : Cannot find an SPWebApplication object with Name, Id, or Url: http://VM-SPWEB.

CategoryInfo : InvalidData: (Microsoft.Share...tWebApplication:SpCmdletGetWebApplication) [Get-SPWebApp

Script halted!

I propose that config files have a contingency checker for required settings.

Looks like you have some invalid or conflicting entries in your input XML. If you post a scrubbed version of the XML here, I or someone else can probably quickly validate it.
