Expected Behaviour

The Chaos Studio target and capability azurerm resources should be created, as the Microsoft.Chaos resource provider is registered in the target subscription.

Actual Behaviour

Terraform apply timeouts after 30 minutes, citing the context deadline has exceeded. This occurs regardless how long you set the deadline for, and the target and capability azurerm resources are not created.

Steps to Reproduce

terraform apply

Thanks for raising this issue. Seems the List API to retrieve target types would time out. The issue Azure/azure-rest-api-specs#30673 is filed for tracking.
