Hi All, I'm getting an error which is stopping me from using pulumi to do anything useful. I have imported a new Azure stack into pulumi from an existing resource group, then created a csharp project and tried

pulumi preview

, but pulumi thinks the resources need to be replaced & stops with an error that the resources are protected. Surely if nothing has changed, then there is no need to replace? If I try to unprotect in the csharp project, then I still receive an error from

pulumi preview

, because the resource is still protected in the stack from the import. How do I unprotect the imported resource? Also, because the preview fails abruptly, I cannot see the replacement steps which pulumi thinks are needed, it seems to be null?

PS> pulumi preview --show-replacement-steps -v 3
