Hi, I get the following error when using the

--target

flag to deploy only one resource to Localstack: I already updated to the latest pulumi packages. As I cannot see my code in the error I cannot figure out what's the problem. Hope someone can help 🙂

target 'urn:pulumi:dev::apps::custom:resource:Account::dev'                                                                   
Previewing update (dev):
     Type                 Name      Plan     
     pulumi:pulumi:Stack  apps-dev           

Resources:
    333 unchanged

Do you want to perform this update? yes
