I’m trying to use

pulumi preview -t urn:xxx --target-dependents

where

xxx

is the parent of some subset of my stack, but I’m getting an error:

Cannot delete parent resource `xxx` without also deleting child `yyy`

I would have thought

--target-dependents

would fix that. Am I missing something or is this possibly a bug?

That sounds like a bug. Do you mind filing an issue with more details?

I don’t have a minimal code example unfortunately but I created this issue with some more detail: https://github.com/pulumi/pulumi/issues/4032
