I'm getting the following error when I try to run the VPP Migration Tool:

I saw from my episerver.config that I had a siteBlockFolderId set to 162, could it be this contentid?. I have tried to change all my sites to use siteBlockFolderId 3 but I still get the same error.

Also I cannot get to my UI after I've followed all steps in the documentation. Could this be related?
