Running into an error when trying to bring down my stack. How do I tell Pulumi to delete the

kable-db-rdsf41604a

before deleting the subnet group?

Diagnostics:
  aws:rds:SubnetGroup (kable-db-sng):
    error: deleting urn:pulumi:staging::kable-infrastructure::custom:resource:DB$aws:rds/subnetGroup:SubnetGroup::kable-db-sng: 1 error occurred:
        * deleting RDS Subnet Group (kable-db-sng-9841ed7): InvalidDBSubnetGroupStateFault: Cannot delete the subnet group 'kable-db-sng-9841ed7' because at least one database instance: kable-db-rdsf41604a is still using it.

Add a dependsOn opt to the database, referring to the subnet group id.
