Failed Deployment Stack Deletion Despite Registered Resource Provider in Subscription

[JaroslawParadysz]

Describe the bug I am unable to delete deployment stacks including a Function App and an App Service Plan, although the Storage Account is deleted successfully. The Activity Log indicates a missing Resource Provider for 'sites' and 'serverfarms', despite having the Microsoft.Web resource provider registered for my subscription.

To Reproduce Steps to reproduce the behavior:

1. Create az deployment stack az stack sub create --name StackTest --template-file environment.test.bicep --parameters environment.test.bicepparam --description "Test Stack" --deny-settings-mode None --location eastus
2. Delete deployment stack az stack sub delete --delete-all true --name StackTest --verbose
3. See error in Function App/App Service Plan Activity Log

Expected behavior Deployment stacks should be deleted successfully.

Has there been any progress, or are there any preliminary findings? Thanks in advance.

Hi @JaroslawParadysz,

There are 2 issues here that we are addressing:

1. The "Object reference not set to an instance of an object" exception being thrown is caused by a bug in our handling of the errored response. We have a fix for this that is checked in and should be rolling out soon.
2. The underlying deletion error is something we are aware of. The resource type Microsoft.Web/sites/config expects deletion from the data plane and does enable deletion from the control plane, which makes deletion here a bit tricky as stack deletion does not use the data plane. We have a thread here in the context of key vault secrets (which are treated similarly) if you would like to read through and see some of our thoughts/suggestions. Feel free to leave additional questions here or on the other thread.
