Error comparing dacpac and WideWorldImporters db

[kisantia]

Repro steps:

1. Create a simple dacpac - ex: a database with one table
2. Set the dacpac as the source
3. Set a WideWorldImporters db as the target
4. Try to compare - get "Object not set to an instance of an object error"

The same comparison works as expected in SSDT

I'm not able to repro this error. I created a dacpac from a database with a single table and compared it to a SQL DB while trying to repro:

I think there was something weird when I first installed the extension and was trying to do schema compare, I wasn't able to get any comparisons working. After restarting vscode, comparisons started working.

It would be helpful if there was a way to see the callstack when there are errors like this, since "Object reference not set to an instance of an object" isn't that useful.
