I'm getting this while making updates to an existing stack. Had to unprotect resources - that's all the extra things I did before the new up run via automation pipeline. Any insights?

error: post-step event returned an error: failed to verify snapshot: resource urn:pulumi:mandtpov::iac-azure::azure-native:resources:ResourceGroup$azure-native:containerservice:ManagedCluster$pulumi:providers:kubernetes$kubernetes:core/v1:Namespace::namespace-asdf refers to unknown provider urn:pulumi:qwerty::iac-azure::azure-native:resources:ResourceGroup$azure-native:containerservice:ManagedCluster$pulumi:providers:kubernetes::aksProvider::2b8c1005-6655-4ab1-bdff-320bc1e8ceca

Are you using inline programs? Typically this means you're referencing a variable from a previous program run (IE global state somewhere in you inline program)
