Hi, Recently I'm getting exceptions regarding empty resource ID. I can create resource but i can't recreate and destroy them. https://github.com/pulumi/pulumi/blob/master/pkg/resource/plugin/provider_plugin.go#L667 https://github.com/pulumi/pulumi/blob/master/pkg/resource/deploy/step.go#L248 I'm wondering if it can be caused by duplicated resource names. Anyone encounterd it? Thanks example message :

empty resource id is

""

?

every resource has some id, but can it be duplicated?

Hi @gray-lawyer-89054 Is this something you can reproduce? I am going to be in that part of the codebase very soon (like later today) so if it's something you can reproduce then I can do something about it

basically it happens every time when i call pulumi destroy in my project but I can't point when this started. I'll try to find reproduce steps

Thanks - please let me know if you find something

Could you open an issue even ahead of having a complete repro? This is definitely a bug we want to fix - at the very least to provide a better error message earlier.
