This message was deleted.

Even more confusing is if I try to delete the parent resource:

pulumi state delete urn:pulumi:dev::vm-scaler::kubernetes:<http://helm.sh/v2:Chart::dd-agent|helm.sh/v2:Chart::dd-agent>

Delete those resources first before deleting this one.

Clearly it is finding that child resource urn.

Very subtle - but these resources include

$

in there name which is likely evaluated by your shell. Make sure to quote the urns.
