Error running post-test destroy - unexpected status 409 with error: RequestConflict: Cannot modify resource

[Orexii]

Hello, I am receiving the following error when trying to run the test TestAccNetAppVolume_updateExportPolicyRule from the main branch of the terraform-provider-azurerm repo. The error seems to be occurring due to calling the function UpdateThenPoll, which I believe is pulled in from this pandora repo. Here is the error:

Any insight on what is causing this would be helpful. My colleague @paulomarquesc is also experiencing this issue when running this test, therefore I am inclined to believe others may experience the issue as well if attempted to be reproduced.

Possible relevant information:

$ terraform version
Terraform v1.7.3
on linux_amd64
$ go version
go version go1.21.6 linux/amd64

hey @Orexii

Thanks for opening this issue.

Taking a look into this one it appears that the API is returning Patching as the value for provisioningState which isn't expected, and is what's causing this error - as such I've opened #888 to fix this one by adding support for that status code.

Since this issue is related to hashicorp/go-azure-sdk (since that's where the Base Layer used by the SDK is located) rather than hashicorp/pandora however, I hope you don't mind but I'm going to move this issue over to that repository.

Thanks!
