Before Stack is Created - stack output command results in Exception Crash

[jestrjk]

I have a project structure where A and B are projects. Each has its own index.ts stack definition.

/A
/A/B

Before updating the /A/B stack, executing from /A:
pulumi --cwd ./B stack output --json returns the Exception reported below

Once I pulumi update the /A/B stack, the stack output --json call works correctly and returns the relevant JSON.

Minor bug, maybe just some more informational error handling needed?
