URLforPortal Error not making any sense

Question

Hello all, 
 
 I don't post often, but this one has me stumped. I'm getting an error in the portal for one environment (Test) with objects that work just fine in another (Dev). I've looked at the supporting objects involved and I cannot see a delta (nor could compare and deploy). Event the portal being referenced in Test works fine except for this one area. I would appreciate advice on what other avenues I should be looking at. Below is the error and script from the 2 environments.

You can check multiple things: Check The portal isn't published in Test or has different permissions. Try a!urlForPortal() Without any parameters. If this works, the issue is with how the portal handles the parameters you're passing. If this doesn't work, then the portal's internal interface likely references something (record type, data store, integration) that's misconfigured in Test.

Anything in the tomcat stdout log file?

You can try Exporting the object and related precedents from dev and import in test manually - without using Compare and Deploy! Check If any inspection errors are there or not. In absence of errors you can deploy and see if it works or reports any errors. Give it a try as Sometimes a Re-deployment can fix or flag the issues not found otherwise.
