sfn update does not fetch values from apply-stack

[autarchprinceps]

I have several different stack updates, which I tried today. They had additional parameters, which dependent stacks definitively do have as outputs, but they are never filled with values, but left empty and to be filled after --defaults.
I had my colleague try, and he suddenly faces the same issues, but even going back to older versions of both sfn and sparkle_formation via Gemfile had no effect.

Hi! I've been testing apply stacks with new stacks as well as with existing stacks. I'm not seeing any issues where values are not applied. Are you still experiencing this issue? If so, would you validate you have correct access to the stacks you are applying.

Thanks!

I have a stack where this happens with sfn 3.1.2 and 3.1.6- there's an output named 'SG' and an input named 'SG' but they don't get slotted together.

I've noticed the same issue and came up with this PR #311. It fixed the issue described in #310
